Rapid Response:

Correction

In my critique of Dr. Vickers' paper, I incorrectly read Figure 2. I
apologize for the erroneous comments drawn from that misreading. Rather
than comparing treatment effects at 28 days, the graph appears to show a
mild benefit of acupuncture in a subset of patients, with other patients,
those with very few or very many headaches (28 days per month), appearing
to show no benefit from acupuncture.

I also note that my comments about statistical sleight-of hand might
have been taken as offensive. They were not intended as such. Other
responses amply demonstrate the problems with both the study and the
statistical interpretations therein, comments with which I wholeheartedly
agree.
