Fig. 4

Forest plot and trial sequential analysis of the hematoma evacuation rate. A Forest plot showing the hematoma evacuation rate in patients with ES versus SBWC. ES showed a superior hematoma evacuation rate compared to SBWC. B The Y-axis represents the z-scores for effect sizes, and the Z-curve (blue line) along the X-axis shows the trend of cumulating evidence toward achieving maximal information. The conventional boundary (dotted black lines) represents the meta-analysis efficacy boundary (|Z| = 1.96, P = 0.05) in the TSA. The cumulative Z-curve crossed the conventional boundary, but the boundary RIS was ignored due to too little information, meaning that the hematoma evacuation rate comparison between ES and SBWC remained inconclusive. CI, confidence interval; ES, endoscopic surgery; RIS, required information size; SBWC, small bone window craniotomy
