Stratified random-effects analysis pooling 5 studies whose target population were all five-year system students (I2 = 92%) found "a statistically significant difference was also observed in skill scores (SMD = 1.08, 95%CI [0.47, 1.69], P = 0.0006) in favor of PBL".

"A statistically significant difference was also observed in skill scores (SMD = 1.08, 95%CI [0.47, 1.69], P = 0.0006) in favor of PBL, compared with the traditional teaching."
