Fig 2 - Effects of psychoplastogens on blood levels of brain-derived neurotrophic factor (BDNF) in humans: a systematic review and meta-analysis

Relationship between effect sizes and the continuous variables of timing, percentage of missing values, and average participant age for studies administering any psychoplastogen. Shading shows 95% confidence intervals. The effect of hours post-administration was significant but minimal (SMD = 0.0005, p = 0.038). Studies with a higher percentage of missing data reported significantly greater effect sizes (SMD = 0.77, p = 0.028).
