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 twelve studies in a random-effects meta-analysis, the mean difference in proficiency score favoured the PBL intervention group over traditional teaching, 0.54 (95% CI 0.18, 0.90). → Luke Alexander Maniangat 2021

q3 · i? · quant-synthesis · r3
Meta-analysis in RevMan 5.3 of twelve studies of PBL-type interventions versus controls for radiographic interpretation skills, using a random-effects model; nine of the twelve studies showed positive mean difference values. The pooled "positive difference of 0.54 (0.18, 0.90)" was statistically significant favouring the intervention group.
"the mean difference in the proficiency score showed a positive difference of 0.54 (0.18, 0.90) with the random effect model based on the heterogeneity value of I2 which was statistically significant favouring the intervention group"
