The 35% CO2 challenge in panic disorder: optimization by receiver operating characteristic (ROC) analysis.

摘要: Abstract To test the power of 35% CO 2 as a challenge for panic disorder (PD), and to set an ideal threshold discrimination between patients controls, we analysed by receiver operating characteristic (ROC) analysis responses 91 out-patients with PD 46 controls who inhaled 65% O gas mixture. ROC confirmed that discriminates well 86% probability classify them correctly on basis subjective anxiety after test. A relatively modest increment in (i.e. absolute 20 units, or relative 26% anxiety) proved be separate two groups our sample.
