The Ethics of “CAM” Trials: Gonzo (Part I)

Blogger’s note: This blog, which is rough going in places, will be presented in either 2 or 3 parts (I won’t know which until next week). I’ll post a part each week until it is complete, but due to overwhelming popular demand I promise to maintain the every-other-week posting of the far more amusing Weekly Waluation of the Weasel Words of Woo/2. Introduction On Feb. 25,...

The Weekly Waluation of the Weasel Words of Woo #2

You Can’t Foo’ Stu with Woo! A Spitzerian (“pointed”) analysis Last week’s inaugural game elicited several amusing and penetrating analyses, including that of the hands-down Gold Medal Winner, Stu. His was the first entry, introduced in a concise and alliterative imperative, and was both hilarious and timely. It implied most of the points discussed by others. This distinctive combination has moved me to grant Stu a legacy here at the W^5....

Misleading Language: the Common Currency of “CAM” Characterizations Part II

Background I promised readers the “Advanced Course” for this week, which undoubtedly has you shaking in your boots. Fear not: you’ve already had a taste of advanced, subtle, misleading “CAM” language, and most of you probably “got” it. That was R. Barker Bausell’s analysis of how homeopathy is “hypothesized to work.” In the interest of civility, let me reiterate that I don’t...

Misleading Language: the Common Currency of “CAM” Characterizations. Part I

The Best Policy From time to time I have been reiterating that correct use of the language has much to do with logic; I should add that it entails also honesty. I use the word “honesty” in its broadest sense… Concision is honesty, honesty concision—that’s one thing you need to know. —John Simon. Paradigms Lost: Reflections on Literacy and its Decline. New York, NY:...

Prior Probability: the Dirty Little Secret of “Evidence-Based Alternative Medicine”—Continued Again

After the previous posting on the Bayesian approach to clinical trial data, several new comments made it clear to me that more needed to be said. This posting addresses those comments and adds a few more observations regarding the unfortunate consequences of EBM’s neglect of prior probability as it applies to “complementary and alternative medicine” (“CAM”).† The “Galileo gambit” and the statistics gambit...

Prior Probability: the Dirty Little Secret of “Evidence-Based Alternative Medicine”—Continued

This is an addendum to my previous entry on Bayesian statistics for clinical research.† After that posting, a few comments made it clear that I needed to add some words about estimating prior probabilities of therapeutic hypotheses. This is a huge topic that I will discuss briefly. In that, happily, I am abetted by my own ignorance. Thus I apologize in advance for simplistic or incomplete...

Prior Probability: The Dirty Little Secret of “Evidence-Based Alternative Medicine”

This is actually the second entry in this series;† the first was Part V of the Homeopathy and Evidence-Based Medicine series, which began the discussion of why Evidence-Based Medicine (EBM) is not up to the task of evaluating highly implausible claims. That discussion made the point that EBM favors equivocal clinical trial data over basic science, even if the latter is both...

Homeopathy and Evidence-Based Medicine: Back to the Future Part V

Homeopathy and Science: Discussion, Summary and Conclusions I was not surprised by a couple of the dissenting comments after Part IV of this blog. One writer worried that I had neglected, presumably for nefarious reasons, to cite replications of Benveniste’s results; another cited several examples of “positive” homeopathy studies that I had failed to mention. I answered some of those points here....

Homeopathy and Evidence-Based Medicine: Back to the Future Part IV

    Homeopathy and Science This week’s entry† is a summary of some of the tests of homeopathy. It is a necessary prelude to a discussion of how homeopaths and their apologists promote the method. Several tenets of homeopathy lend themselves to tests. The doctrine of similia similibus curantur (“like cures like”) was tested by Hahnemann himself, as introduced in Part I...

Annals of Questionable Evidence: a new study reveals substantial publication bias in trials of anti-depressants

Part IV of the ongoing Homeopathy series will have to wait a day or two, because it is superceded by a recent, comment-worthy publication. Nevertheless, “H series” fans will find here a bit of grist for that mill, too. An important role for this blog is to discuss problems of interpreting data from clinical studies. Academic medicine has committed itself, on the...
