Meta-analysis pooling comprehensive ability scores from 11 included RCTs (441 CBL and 439 LBL students), random-effects model. The pooled effect size SMD=2.91 (95% CI 1.74 to 4.07) with heterogeneity I2=98%. Note the abstract prints 1.91 while the Results section prints 2.91.

"The meta-analysis of the comprehensive ability scores found that the CBL teaching model significantly increased comprehensive ability scores by a mean of 2.91 compared with that of the LBL teaching model (95% CI: 1.74 to 4.07; p<0.0001)."
