Subclaims

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q3 i2 PBL + CBL, PBL + CP, CBL + WeChat, TBL, PBL, PBL + EBM and CBL each show significantly higher theoretical scores than LBL, with SMDs from 0.98 to 2.07. → Guan Cheng Ye 2025

In the theoretical-score NMA (72 studies, 4874 trainees), seven interventions each beat LBL significantly (P < 0.05), with printed SMDs and 95% CIs as quoted.

"PBL + CBL method (SMD = 1.61, 95% CI [1.12, 2.1]) PBL + CP method (SMD = 2.07, 95% CI [0.81, 3.34]), CBL + Wechat method (SMD = 1.74, 95% CI [0.5, 2.99]), PBL + Wechat method (SMD = 2.3, 95% CI [1.19, 3.42]), TBL method (SMD = 1.57, 95% CI [0.28, 2.85]), PBL method (SMD = 1.35, 95% CI [0.78, 1.92]), PBL + EBM method (SMD = 1.28, 95% CI [0.3, 2.25]) and CBL method (SMD = 0.98, 95% CI [0.21, 1.75]) have significant advantages"
