To the Editor: Ms Savoye and colleagues1 described a randomized controlled trial studying the effects of a weight management program on body composition and metabolic parameters in overweight children. The results were reported as changes in the means and standard deviations for the intervention and control groups. Although the results suggest a benefit of the intervention, it is difficult to derive useful information such as a number needed to treat (NNT) from these results.
