title: A trend analysis of changes during treatment of panic disorder with alprazolam and imipramine.
abstract: A total of 123 Scandinavian patients participated in a cross-national study of panic disorder. Twelve outcome measures, including number of panic attacks and phobias, have been used to describe changes in symptoms during treatment. This article gives a trend analysis of remission for each variable, analysing changes through the total period from baseline to week 8 and also changes in first and second half of this period, separately. Important differences between treatments are demonstrated. Alprazolam had an early effect on variables relating to panic attacks, such as severity of spontaneous attacks and avoidance, whereas imipramine showed a more delayed effect on global measures. Duration of illness, sex and the occurrence of depression in patients' history all affected the sequence of improvement.
