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 i? Versus LBL, 3D-PBL improved self-directed learning ability most (MD 8.40, 95% CI 6.42 to 10.40), followed by MDT-CBL (MD 4.97). → Gu Peng 2026

Gu Peng 2026¶
Gu Peng, Xu Zhendong, Zhang Zheng, Wen Yonghao, Jia Yanqing, Du Ying, Wen Tianlin, Man Chao, Jia Zhiwei, Wu Yaohong, Li Wei. (2026). Comparative effectiveness of orthopedic teaching methods in China: a Bayesian network meta-analysis of randomized trials. BMC Medical Education. https://doi.org/10.1186/s12909-026-08582-4
q3 · i? · quant-synthesis · r2
Network meta-analysis of self-directed learning ability from 8 studies, covering 6 teaching designs and 15 comparisons; the printed mean differences versus LBL are reported, and 3D-PBL was rated high-quality evidence.
"Compared to LBL, 3D-PBL (MD 8.40, 95% CI 6.42 to 10.40) showed the greatest improvement in self-directed learning ability, followed by MDT-CBL (MD 4.97, 95% CI 3.09 to 6.88)."
