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 communication skills most (MD 3.61, 95% CI 2.43 to 4.78), followed by 3D-CBL (MD 1.63). → Gu Peng 2026

q3 · i? · quant-synthesis · r3
Network meta-analysis of communication and expression ability from 8 studies, covering 5 teaching designs and 10 comparisons; the printed mean differences versus LBL are reported, and 3D-PBL was rated high-quality evidence.
"Compared to LBL, 3D-PBL (MD 3.61, 95% CI 2.43 to 4.78) showed the greatest improvement in communication skills, followed by 3D-CBL (MD 1.63, 95% CI 1.20 to 2.06)."
