Objective To evaluate the effect of problem-based learning (PBL) versus tradi-tional methods in medical statistics. Methods Computer retrieval was conducted to search for con-trolled studies comparing PBL and traditional methods. The quality of included studies was critically evaluated and data were analyzed by using the Cochrane Collaboration's RevMan 5.0 software. Results A total of 21 articles were retrieved, but only 7 were included. The results of Meta analysis showed that there was no significant difference between PBL and traditional methods in both the passing rate of student's score (RR=1.09, 95%CI=0.98-1.23, P=0.12>0.05) and the exact score (WMD=0.30, 95%CI=-0.06 -0.67, P=0.10>0.05). Conclusion PBL showed no better learning results in medical statistics compared with traditional methods.
