Tests for publication bias indicating that there was no sign of any missing study and, therefore, the estimate of the combined risk ratio remained unchanged (no publication bias).
| Testa | Results |
|---|---|
| Egger's test of the intercept | Intercept (B0) is 0.22971, 95% confidence interval (−1.19571, 1.65513), with t=0.36455, degree of freedom = 9. The 1-tailed P-value (recommended) is 0.36193, and the 2-tailed P-value is 0.72387 |
| Begg and mazumdar rank correlation test | Kendall's tau b (corrected for ties, if any) is −0.32727, with a 1-tailed P-value (recommended) of 0.08056 or a 2-tailed P-value of 0.16112 (based on continuity-corrected normal approximation) |
