From: Thyroid autoimmunity and IVF/ICSI outcomes in euthyroid women: a systematic review and meta-analysis

a Overall association between thyroid autoimmunity and mean number of embryos transferred. Results showed no significant difference in number of embryos transferred between TAI+ and TAI- women overall (SMD 0.02; 95%CI [− 0.18, 0.22]; P = 0.85; 5 studies; I2 = 69%). b Association between thyroid autoimmunity and mean number of embryos transferred in euthyroid women. Results showed no significant difference in number of embryos transferred between TAI+ and TAI- euthyroid women (SMD 0.07; 95%CI [− 0.13, 0.23]; P = 0.49; 3 studies; I2 = 0%). TAI+, thyroid autoimmune; TAI-, not thyroid autoimmune; SMD, standard mean difference; CI, confidence interval
