^#p < 0.001, based on the Wilcoxon rank sum test.

*p = 0.1, based on the Wilcoxon rank sum test. The medications were assumed to have the same efficacy to treat symptoms of the diagnoses: 40–60% effectiveness for patients, while placebo worked for 20% to 40% of the patients (17).

^∧p = 0.16, compared with the confidence in the diagnosis of major depressive disorder based on symptoms (Q3) using the Wilcoxon rank sum test. SD, standard deviation.
