Subclaims¶

q3 i3 The nursing-only subgroup showed a higher SMD of 2.368 (95% CI 2.05–2.6, I2 = 48%) versus SMD = 1.92 for the others subgroup. → Ngoc Phan Nguyen 2020 q3 i? The test of subgroup differences was not statistically significant (p = 0.1), possibly due to fewer studies in the nursing-only subgroup. → Ngoc Phan Nguyen 2020 (2)

Evidence¶

Ngoc Phan Nguyen 2020¶

Ngoc Phan Nguyen, Cheng Chao-Ling, Lin Yen-Kuang, Wu Ming-Shun, Chu Jan-Show, Tang Kung-Pei. (2020). A meta-analysis of students’ readiness assurance test performance with team-based learning. BMC Medical Education. https://doi.org/10.1186/s12909-020-02139-9

q3 · i3 · quant-synthesis · r2

Subgroup analysis of the meta-analysis comparing the nursing-only subgroup with the others subgroup; the nursing-only subgroup's "higher SMD of 2.368" came with reduced heterogeneity (I2 = 48%).

"the group that comprised only nursing students showed a higher SMD of 2.368, 95% CI = 2.05 ~ 2.6, pheterogeneity =0.14, and I2 = 48% (Fig. 3)."

q3 · i? · quant-synthesis · r2

The meta-analysis's formal test of subgroup differences between nursing-only and others subgroups was non-significant; the authors note the nursing-only subgroup contributed smaller numbers of studies and participants.

"There were no statistically significant subgroup differences (p = 0.1 in Fig. 4). However, smaller numbers of studies and participants contributed data to the nursing-only subgroup than to the others subgroup"

• Students in healthcare-professions TBL achieve significantly higher GRAT scores than IRAT scores (pooled SMD = 2.05) — a broader claim this one bears on
