A general record of my ongoing battle with all forms of nonsense.

The justification for my complaints is simply that there is no evidence that chiropractic is an effective treatment for infant colic. For the purpose of clarity, I'd like to add that there is also no evidence that chiropractic can help alleviate the symptoms of infant colic.
But some criticism has pointed out that I'm not suggesting an alternative treatment, and while no evidence-based treatment for infant colic exists, it makes sense to use a treatment with no evidence for its effectiveness.
I will now explain why this position is wrong.
What do we mean by "no evidence"? We mean, simply, that there is no sensible reason to believe that a given intervention is effective. There is no evidence that bathing your child in tomato juice is an effective treatment for infant colic. There is no evidence that hanging your child upside down for two hours a day is effective in alleviating the symptoms of infant colic. These might sound like strange things to suggest, but that's my point: there is no evidence base for these being effective. Chiropractic, as an intervention for treating colic, is no different in this respect.
I am aware that chiropractors do use chiropractic as a treatment for colic, but this isn't a reason to suspect it may work.
Some chiropractic colleges teach that chiropractic is effective in treating colic, but this isn't a reason to suspect it may work.
Some chiropractors notice that symptoms of colic appear to subside after chiropractic treatment. But this is equally consistent with the hypothesis that it is ineffective: we know that symptoms subside over time without treatment anyway.
Until there is a valid reason to suspect that chiropractic may be effective in treating colic, chiropractic as a treatment stands equal beside bathing your child in tomato juice and hanging your child upside down.
But chiropractic takes it one stage further. Because despite the fact that there is no evidence to suggest that bathing your child in tomato juice is effective, nobody has ever tried to look for the evidence. With chiropractic, the evidence has been searched for. Double blind trials have been performed. And they have failed to show it is effective.
If there are three hypotheses, all without evidence for them and one where evidence has been looked for but not found, then that one is clearly the least plausible hypothesis.
There are billions and billions of possible things you could do to a small child that might be effective in alleviating the symptoms of infant colic. Only a tiny fraction of them will work. It is completely unreasonable to suggest that any one of those billions of possible treatments may work without some sort of evidence. If you've looked for evidence that one of those billions of treatments works and failed to find it, then it is completely irresponsible to promote it as a treatment - especially, when like most interventions, it is not 100% safe.
With my complaints, I am not trying to deny patients the right to try whatever they want as a treatment. What I am trying to prevent is a group of people profiting by telling their patients that their treatment is effective when there is not only no evidence - but there is actually evidence to the contrary.

Tomorrow there is a debate in parliament on the subject of libel reform.
English libel laws are being used to stifle scientific debate in the UK, to the point where many scientists are not bothering to make their opinions heard. Those that do criticise others are being heavily punished for doing so.
Medical doctor and journalist Ben Goldacre was recently involved in a libel battle following his criticism of a vitamin salesman who claimed that anti-retroviral drugs were ineffective in treating AIDS and offered his vitamins as an alternative. Despite the fact that Goldacre won, they still came out of it £150,000 poorer. The science author Simon Singh is going through a similar situation right now.
In 1961, the German paediatrician Widukind Lenz criticised the drug Thalidomide. By this time, at least 10,000 children had been born with birth defects. If he, and all other scientists since, had refused to make their criticism known for fear of legal action, the deformities may still be continuing today.
If we put a stop to criticism, we not only put an end to our ability to know which of our current treatments are effective and safe, but we also make it impossible to evaluate the treatments of the future.
We must do everything we can to reform our uniquely repressive English libel system.
The future health of everyone in this country and the world depends on it.

"We would have hoped they would have taken this down by now."
"I notice that despite your informal resolution with the ASA, that the text still appears on your patient information leaflet here: http://www.gcc-uk.org/files/link_file/WhatCanI_142_5(Web-Version).pdfAre you intending to take down or change this leaflet?"
"I contacted the GCC following my finding that they had not removed the Patient Information Leaflet from their web site. I had a rather surprising reply from them this morning. They said that they will take it down in reasonable time - and suggested that this would happen once they had taken the time to re-write the document and translate it into several languages.This is shocking. Surely it makes sense for them to take it down now if it breaches ASA standards - or not at all if it doesn't. Surely while they are re-printing they should not be continuing to distribute the material?Can you clarify the ASA's position on this?"
"We’d normally expect an advertiser to implement the changes as soon as is 'reasonably practicable' (bearing in mind the time involved in printing new leaflets).However, if it’s a leaflet on a website then it should be taken down as soon as possible."
- The Chief Executive of the GCC is fully aware that its Patient Information Leaflet violates ASA guidelines.
- The Chief Executive of the GCC is aware that this leaflet is continuing to be made available on their web site.
- The Chief Executive of the GCC is in no rush to do anything about it.

My complaint to the Advertising Standards Authority about the General Chiropractic Council’s Patient Information Leaflet has now gone through the ASA’s process.
The ASA has managed to deal with my complaint as an “Informally Resolved Complaint” rather than pushing it through to a formal adjudication.
This is a very interesting outcome.
What this means is that the General Chiropractic Council has withdrawn the claims as soon as they were approached and asked the ASA’s guidance in how they can make their advertising comply. There is an important point to note here: if the General Chiropractic Council believed they had the evidence to back up the efficacy of using chiropractic as a treatment for asthma, headaches, migraine and infant colic – then they simply could have produced it.
The ASA would have assessed this for them free of charge and either upheld the complaint asking them to remove the advertising, or not upheld the complaint. There is only one reason for backing off from the complaints: the GCC must have appreciated that that they simply do not currently have the evidence.
This is a significant change, and has huge implications for the circa 600 complaints currently being handled by the GCC.
By backing off and removing their claims before the ASA investigates, the GCC is acknowledging that even their loosely worded, slightly ambiguous leaflet (text below) is in breach of ASA guidelines.
There is some evidence, though more research is needed, that you may see an improvement in some types of:
• headaches, including migraine
• infant colic.
If the GCC believes this loosely worded text to be in breach of ASA guidelines, then they must also believe that every complaint made to the GCC surrounding this subject is valid.
Am I being too optimistic in anticipating a vast number of guilty verdicts against chiropractors in the forthcoming months?
It also brings up a second potentially interesting outcome. If you’ve been following this blog, you will be aware of the letter that the GCC sent to Trading Standards in defence of their members. The advice given in that letter includes the exact text within the patient information leaflet that I complained about.
Will the GCC now follow that letter up with another saying that they are now withdrawing that claim? I will be putting that question to them.
Perhaps I'm being a bit optimistic – especially considering that more than a week after agreeing to informally resolve the complaint, the patient information leaflet remains on their website in its original form.
I am now beginning work on my second ASA complaint about the same Patient Information Leaflet.
While you're in the mood for chiro woo, I highly recommend Zeno's post on his recent ASA complaint - published at the same time.
