Publication bias and sensitivity analysis
Egger’s test (t =1.35, p =0.226) indicated no significant
publication bias was found across the included studies for CD.
Meanwhile, Egger’s test (t =1.92, p =0.097) also did not
find significant publication bias in studies for UC.
Figure 4 shows the outcomes of the sensitivity analysis. The results
were not significantly changed after checking the overall effect by the
leave one out method, suggesting that the meta-analysis results were
stable.
