Subclaims¶

q3 i? Deleting any single study left the significant TBL effect unchanged (SMD range 2.26–2.67), and a fixed-effects model yielded a consistent significant effect (SMD = 1.63). → Chen Minjian 2018 q3 i? Begg's test did not reveal funnel plot asymmetry (P = 0.059), making publication bias unlikely. → Chen Minjian 2018

q3 · i? · quant-synthesis · r2

Sensitivity analysis in which each of the 13 studies was deleted in turn; the significant TBL effect was unchanged (SMD 2.26–2.67). A fixed-effects model also gave a significant effect (SMD = 1.63, 95% CI: 1.51–1.76), and Begg's test gave P = 0.059.

"When any research was removed from the model, the significant results of TBL effect on the students’ examination scores were unchanged in these models (SMD: 2.26–2.67, 95% CI: 1.32–3.67, n = 13)"
