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 i3 Thirteen studies (1090 students) showed a significant difference in skill scores in favor of PBL (SMD = 2.10, 95% CI [1.38, 2.83]). → Zhang Song 2018

Zhang Song 2018¶

q3 · i3 · quant-synthesis · r3
Meta-analysis of 13 studies involving 1090 medical students (PBL group = 545, control group = 545), pooled with a random-effects model due to significant heterogeneity (I2 = 95%, P < .00001). Skill tests assessed "clinical practice for film reading."
"The result showed a significant difference in skill scores (SMD = 2.10, 95% CI [1.38, 2.83]) in favor of PBL, compared with the traditional teaching"
