Drug Treatment of Panic Disorder: Comparative Efficacy of Alprazolam, Imipramine, and Placebo: Cross-National Collaborative Panic Study, Second Phase Investigators
Abstract
The Cross-National Collaborative Panic Study, Phase Two, compared alprazolam with imipramine and with placebo in a sample of 1168 randomly assigned subjects. The study, conducted at 12 centres, assessed clinical change over eight weeks of double-blind drug treatment. Improvement occurred with alprazolam by week 1 and 2, and with imipramine by week 4. By the end of week 8, however, the effects of the two active drugs were similar to each other, and both were superior to placebo for most outcome measures.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
