This forest plot illustrates the between-arm differences in the Hamilton Anxiety Rating Scale (HAM-A) improvement from baseline to final evaluation across various studies comparing Alprazolam to benzodiazepines such as Etizolam, Lorazepam, Diazepam, and Alprazolam XR. The analysis presents the weighted mean difference (WMD) point estimates with 95% confidence intervals (CIs) for each comparator, highlighting the overall effectiveness of Alprazolam (I² = 0.97, p < 0.01). The results suggest that Alprazolam may have superior therapeutic effects compared to its comparators.
