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.
q4 i1 PBL subgroup analysis showed a significant but small effect versus LBL (SMD = 0.33, 95% CI 0.01-0.65, P = .045). → Pang Xuefei 2024

q4 · i1 · quant-synthesis · r3
Subgroup analysis by teaching method (Figure 3B) in the meta-analysis; PBL appeared as the experimental method in 6 studies. The pooled PBL effect was significant at P = .045 with a confidence interval (0.01-0.65) barely excluding zero.
"PBL (SMD = 0.33, 95% CI = 0.01-0.65, P = .045) and FC (SMD = 0.50, 95% CI = 0.31-0.69, P < .001) had significantly higher teaching effects than traditional teaching method LBL"
