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 i? The pooled Pearson correlation between station scores was 0.27 (95% CI: 0.15, 0.39) with high heterogeneity, indicating students who perform well on one station do not necessarily perform well on others. → Bobos Pavlos 2021

Random effects meta-analysis of Pearson correlations between OSCE station scores across included studies. The pooled estimate was "0.27 (95% CI: 0.15, 0.39)" with high heterogeneity I2 = 71.55%. No standardised effect size was printed for this finding.
"The pooled estimate of Pearson’s correlation in between station score correlation was 0.27 (95% CI: 0.15, 0.39) with high statistical heterogeneity, I2 = 71.55% (Fig 4)."

Related Claims¶
- Canada (excluding Quebec) is the only country of 17 requiring a clinical competency examination for licensure of domestic physical therapy graduates — related
- OSCEs used with physical therapy students show weak internal consistency, with a pooled Cronbach's alpha of 0.55 below the acceptable range — related
- Each OSCE station score correlates strongly with the total OSCE score, with a pooled Pearson correlation of 0.71 — related
- OSCE designs with 5-10 stations achieve good internal consistency (Cronbach's alpha = 0.83), outperforming designs with fewer than 5 or more than 10 stations — related
