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? Across pooled controlled studies, the PBL experimental group produced a significantly higher course examination excellence rate than the LBL control group (RR = 1.66, 95% CI 1.33–2.06). → Zhang Yanqi 2015

q3 · i? · quant-synthesis · r3

Meta-analysis of nine studies reporting excellence rates (scores ≥80), using a random effects model after moderate heterogeneity (I2 = 68%, P = 0.001). The result shows "a significantly higher course examination excellence rate than the LBL control group" with RR = 1.66. Average excellence rates were 51.6% versus 31.1%.

"the analytical results reveal that the experimental group produced a significantly higher course examination excellence rate than the LBL control group [RR: 1.66, 95% CI: (1.33, 2.06)]"
