From: Thyroid autoimmunity and IVF/ICSI outcomes in euthyroid women: a systematic review and meta-analysis
a Overall association between thyroid autoimmunity and mean maternal age. Results showed no significant difference in mean maternal age between TAI+ and TAI- women overall (SMD 0.12; 95%CI [− 0.04, 0.28]; P = 0.15; 13 studies; I2 = 76%). b Association between thyroid autoimmunity and mean maternal age in euthyroid women. Results showed no significant difference in mean maternal age between TAI+ and TAI- euthyroid women (SMD 0.13; 95%CI [− 0.10, 0.36]; P = 0.25; 10 studies; I2 = 82%). TAI+, thyroid autoimmune; TAI-, not thyroid autoimmune; SMD, standard mean difference; CI, confidence interval
