q3 i? In subgroup analyses, CBL was most effective for clinical course knowledge (SUCRA 97.7%) and across educational backgrounds, whereas PBL led for theoretical scores in developing countries (86.6%) and basic courses (78.3%), and remained optimum for operational skills in all subgroups. → Zhang Shuai-Long 2024

Subgroup analyses by region, curricula, and educational background within the NMA. The article also reports "CBL emerged as the most effective method for improving proficiency in clinical course knowledge with a probability of 97.7%" and superior performance regardless of educational background; further subgroups could not be conducted due to limited studies.

"Notably, PBL was found to be particularly effective in enhancing theoretical test scores in developing countries with a probability of 86.6%, as well as in basic courses with a probability of 78.3%."

Related Claims¶

• CBL is the most effective method overall for both theoretical and practical neurology teaching outcomes, with no evidence of publication bias — reports the opposite
• CBL shows the largest effect on theoretical exam scores versus LBL (MD = 13.12) and ranks first among the seven methods — related
• CBL is the highest-ranked strategy for enhancing medical students' theoretical test scores, with CBL, PBL, SBL and FC each significantly outperforming LBL — related
• For practical skills, EBM shows the largest effect versus LBL (MD = 13.34) and the ranking is CBL > EBM > PBL > TBL > FCM > CP > LBL — reports the opposite
• CBL improved exam scores in both basic theory and applied psychology course subgroups, but course type did not explain the heterogeneity — related
• CBL effects differ between theoretical and practical courses for knowledge, skill and comprehensive ability scores — related
• Subgroup analyses by intervention duration and region reduce heterogeneity only for interventions longer than six months and Western countries, without significant PBL differences in any subgroup — related
