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.
q2 i? Sensitivity analyses by country and leave-one-out iterations leave the CBL exam-score advantage statistically significant, while the funnel plot suggests potential publication bias. → Chen Min 2025

q2 · i? · quant-synthesis · r2
Sensitivity analysis of the exam-performance outcome across the included RCTs. Subgroup analysis by country remained consistently significant, indicating region was not a primary source of heterogeneity; leave-one-out SMDs ranged 0.52–0.62, all P < 0.05.
"Between the studies in China, the pooled effect size remained statistically significant across all iterations when leave-one-out approach (SMD = 0.52–0.62, all P < 0.05). Thus, the overall effect remained stable and statistically significant"
