Complementary Treatment of Varicose Veins: A Randomised, Placebo-controlled, Double-b

I am after a copy or a link to this study:

Phlebology (The Royal Society of Medicine Press, UK)
“Complementary Treatment of Varicose Veins: A Randomised, Placebo-controlled, Double-blind Trial”

E. Ernst, T. Saradeth, K.L. Resch, 1990, 157-163.

I asked Prof. Edzard Ernst about it and he confirmed that it provided a positive result, though only so much can be communicated with ease via Twitter.

Can't seem to find an online version; perhaps someone will have some better resources than I?

This study of 61 patients showed a 44% improvement in venous filling time in the homeopathic treated group when compared with placebo.
Best I can find, but without the full paper, impossible to see what they did to get that result.

I'll bet $20 that the study was flawed and the results are not repeatable...

Um, was the placebo also a fluid? Because if it wasn't then the entire study is bogus. You can get those sorts of numbers just by changing fluid intake.

I will be interested to see any more information about the testing procedures.

That's as far as I can get; i am weary of the claimed results because they ONLY appear on pro-homeopathy website. I want to see the conclusions from the authors - more importantly, the entire study.

Results may very well have been a statistical anomaly; though I agree - unlikely to be replicated.

Given the positive results and reportedly good methodology, one wonders why this study does not get more homeopaths attempting to replicate it.

Without seeing the study, I expect it to be a fairly good study - being from Edzard Ernst.

The homoeopaths are still desperately trying to discredit him. They can't possibly cite it.

Only 65 subjects, and over 20 years old - has nobody tried a replication with a bigger sample size over the last couple of decades?

I think there is a bit of a mix up. The only article I can find from Ernst and co. on varicose veins is this one: A single blind randomized, controlled trial of hydrotherapy for varicose veins.
It is not a study on homeopathy, and it was not placebo controlled. I don't think it is available online, so we will have to settle with the summary.

I can't track down the paper that Acleron found (a mentioning of), but the number of patients enrolled was the same, suggesting that we really are talking about the same study.

I smell a rat. 'Scientific Research in Homeopathy', a Knol by Nancy Malik, gives this:
Quote:
8. Phlebology (The Royal Society of Medicine Press, UK)
"Complementary Treatment of Varicose Veins: A Randomised, Placebo-controlled, Double-blind Trial" E. Ernst, T. Saradeth, K.L. Resch, 1990, 157-163.
Over a period of 24 days, the effects of a homeopathic complex preparation and placebo on varicose veins were tested in a double-blind trial of 61 people suffering from this condition. The homeopathic complex produced an averaged 44% improvement in the condition while those given the placebo experienced an averaged worsening of the disorder.
Same authors, same number of patients, same trial length... This entry by Malik is referenced by many homeopathic blogs, forums, and sites.

ETA: I couldn't find any articles of that name or with those authors in a search of the 'Phlebology' journal on the The Royal Society of Medicine Press site.

If you try to browse their online archive, it only seems to go back as far as 2003 (when they seem to have changed publisher - the first article there is called "Change of publisher and Editor - a new era"), so most likely it's just too old.

Articles in Phlebology were not Pubmed indexed until 2007, which makes it even harder to check out. I can't access EMBASE from home, so I will have to wait until Monday unless anybody else have access.

I still think the similarities between the summaries of the "two" papers look suspicious. None of this changes the fact that one positive study does not constitute proof. I would think that it would be worthwhile for homeopathic practitioners to replicate a positive study. Publication bias can definitely not be ruled out.

Come on Mojo. Do you really think that they don't understand that a single positive study does not constitute proof?

I suspect they are also aware that larger trials are less likely to produce positive results.

When I asked Ernst about the study, I cited the name of the study - I date say I I had got it wrong, he would have corrected me on it.

As has been noted, the publisher changed and it seems no one has access to this document without the actual journal itself.

Makes one wonder what passes for an assessment when so many homeopaths have cited as evidence, when it is a study they have not read - or have access to.

I will ask Malik to provide a copy.

I wouldn't hold your breath; she seems quite able to post studies that she evidently hasn't read (most notoriously the Nuremberg salt trial).

But the title doesn't even mention homeopathy. It could be an article on the effects of chestnut seed extracts, which indeed have shown positive effects in a couple of studies.

Another oddity is the omissions from the abstract. If you look at the abstract from the hydrotherapy study it says
Quote:
In conclusion this controlled study implies that hydrotherapy may help patients suffering from primary varicose veins.......
This tells us how much weight the authors feel that the positive result of the study has. Assuming that the paper exists, Malik has not shown us what the authors conclude.

I have been asking around, and someone got in touch with Ernst. This is what he wrote:
Quote:
The homeopathic study did take place. We tested a remedy that contained several plant substances in undiluted form. So,it was only nominally a homeopathic preparation.
So it was not a positive homeopathy study after all.

I can't even get a hit on it off Google Scholar. The only source of it at all is this post about, Scientific Evidence for Homeopathic Medicine.

If it worked and could be replicated, there would be more work that followed it up...unless of course the super secret super duper Global government and their reptilian overlords at the Federal Reserve Board...or at least something like that...

...I forgot, there has to be Da' Jooz' is 'dere somewhere.

OK. So we'll ignore it just a teeny, weeny, its-see-bits-see, infinitesimally small bit? I'll have mine with scotch, not water, please.

Surely scientific papers on homeopathy should be more effective with fewer words, with the most effective being a stack of blank paper without a molecule of ink between them.

Don't know. The only thing that smells like homeopathy is the company name (as far as I can see). But I have seen homeopathy studies cleverly "camouflaged" as studies on effect of real substances.

Gits!

Ernst isn't a great fan of homeopathic cancer "treatments":

... there is no reason to believe that homeopathic medicines have anything to offer to patients suffering from cancer or other conditions apart from non-specific effects.

True - but if somebody else publishes for you, you might as well use it to your advantage.

Boiron market themselves as manufacturers of homeopathic remedies. Categorising it as a homeopathic remedy if it works under clinical testing conditions and as a non-homeopathic remedy if it fails under clinical testing conditions make sense from a conspiratory theoretical point of view
