Figure 2. Differences between intervention groups (Esketamine, n = 26, and Ketamine, n = 27) over time. A) MADRS mean scores at the different time points, B) BDNF serum levels at the different time points. Error bars represent 95% confidence intervals of means. BDNF = brain-derived neurotrophic factor; MADRS = Montgomery-Åsberg Depression Rating Scale.
