Forest plot for the effect of TBL on theoretical examination scores compared with LBL. Studies are plotted according to the last name of the first author and followed by the publication year in parentheses. Horizontal lines represent 95% CI. Each square represents the SMD point estimate, and its size is proportional to the weight of the study. The diamond (and broken line) represents the overall summary estimate, with confidence interval given by its width. The unbroken vertical line is at the null value (SMD = 0). CI, confidence interval; SMD, standardized mean difference
