In Reply: Mr Chen and colleagues call attention to potential demographic and clinical characteristics that may have affected the outcome in our randomized controlled trial of CBT among older adults with generalized anxiety disorder. Although we did evaluate a number of patient characteristics that may have differed among patients randomly assigned to CBT and EUC, they point out other variables that we omitted from these comparisons but that might have had an effect.
