Error in Figure. In the Clinical Trials article by Seltzer et al titled “Efficacy of Donepezil in Early-Stage Alzheimer Disease: A Randomized Placebo-Controlled Trial,” published in the December issue of the ARCHIVES (2004;61:1852-1856), an error occurred in Figure 3 on page 1854. For the y-axis of that figure, the numbers below the zero should have been negative and the numbers above it should have been positive. The corrected figure is reprinted here with its legend.
Mean ± SE change from baseline through 24 weeks of treatment on the Mini-Mental State Examination (MMSE) score for the donepezil and placebo groups. The difference between groups was as follows: P = .02 at week 6, P = .04 at week 12, P = .03 at week 24, and P = .002 at the end point. LOCF indicates last observation carried forward.
