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 four included studies, the pooled mean difference in knowledge score favoured the PBL group over the TT group, 4.15 with a range of -0.35 to 8.65. → Luke Alexander Maniangat 2021

q3 · i? · quant-synthesis · r1
Random-effects meta-analysis of four studies (116 PBL and 117 TT students) assessing knowledge scores. The forest plot "demonstrates a significant difference in mean knowledge score between the PBL group and the TT group in all included studies".
"The implant mean difference in the knowledge score for 116 and 117 students in the PBL and TT groups, respectively, in the included four studies [20, 22, 24, 25] was 4.15 with a minimum and maximum of -0.35 and 8.65, respectively."
