Figure 3: Non-inferiority representation of the difference (homeopathy versus fluoxetine) in the mean change of the MADRS scores on the 4th and 8th weeks of randomized, double-bind treatment. Error bars indicate two-sided 95% CIs. Tinted area indicates zone of non-inferiority. Delta indicates the margin of non-inferiority. Mean differences (homeopathy-fluoxetine) were −3.04 (−6.95 to 0.86) and −2.64 (−6.05 to 0.77) at weeks 4th and 8th, respectively.
