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, MDT-CBL improved clinical reasoning most (MD 3.00, 95% CI 1.34 to 4.65), followed by 3D-CBL (MD 2.58) and 3D-PBL (MD 1.82). → Gu Peng 2026

q3 · i? · quant-synthesis · r3
Network meta-analysis of clinical reasoning from 14 studies, covering 6 teaching designs and 15 comparisons; the printed mean differences versus LBL are reported, with MDT-CBL and 3D-CBL rated low-quality evidence while 3D-PBL was rated high quality.
"Compared to LBL, MDT-CBL (MD 3.00, 95% CI 1.34 to 4.65) showed the best improvement in clinical reasoning, followed by 3D-CBL (MD 2.58, 95% CI 2.01 to 3.14) and 3D-PBL (MD 1.82, 95% CI 1.67 to 1.96)."
