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.
q2 i? The nine included studies were all non-randomized, eight were rated moderate quality, and heterogeneity exceeded 75% across all three outcomes. → Ji Pengyu 2026
Evidence¶
Ji Pengyu 2026¶
Ji Pengyu, Li Qianqian, Li Na, Zhang Lin. (2026). The efficacy of bilingual immunology teaching on undergraduates in China: a systematic review and meta-analysis. BMC Medical Education. https://doi.org/10.1186/s12909-026-08725-7
q2 · i? · quant-synthesis · r1
Quality assessment of the nine included non-randomized studies using MINORS (12 items, graded low 0–8, moderate 9–16, high 17–24) and ROBINS-I V2 for risk of bias; one study showed low risk, eight moderate risk, none high or critical.
"The methodological quality of eight studies was rated as moderate, while one study was assessed as high quality."
