(A) Pooled risk difference (95% CI) of ROM in all 13,752 thyroidectomies when considering NIFTP as non-malignant entity rather than malignant. The vertical line at point zero of the x axis represents the absence of difference. The result shows that if NIFTP is considered as a non-malignant tumor, the ROM is reduced by 5.5% (95% CI from 3 to 7). I2 (inconsistency) was 78.6% (95% CI = 54.6–87.2%). (B) As shown in funnel plot, a publication bias might be considered. Egger test: P = 0.067.
