marginally significantP = 0.088
Although there was marginally significant publication bias for prudent dietary pattern studies (Begg’s test P = 0.088, Egger’s test P = 0.049), no evidence of publication bias was observed after using the trim-and-fill method (Begg’s test P = 0.687, Egger’s test P = 0.975), and the association remained significant (RR 0.87, 95% CI 0.79, 0.97, P = 0.009).
