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? Pooled across six RCTs, PBL groups scored significantly higher than LBL groups on overall DREEM scores (WMD 9.10, 95% CI 5.98–12.21, p < 0.00001). → Qin Yongjie 2016

q3 · i? · quant-synthesis · r1
Random-effects meta-analysis of six RCTs (pooled n = 673; PBL 335, LBL 338), all conducted in China between 2006 and 2013, using Revman 5.3. The pooled weighted mean difference favored PBL: "WMD 9.10, 95% CI 5.98–12.21, p < 0.00001". Moderate heterogeneity (I2 = 61%, p < 0.10) was reported.
"Compared with the control LBL group, the pooled effect size showed a significant difference in medical educational environment scores (WMD 9.10, 95% CI 5.98–12.21, p < 0.00001) in favor of the PBL group"
