From: TSH levels after fresh embryo transfer are associated with reproductive outcomes in euthyroid women undergoing the first IVF/ICSI cycles

Figure 2

The relationship between the D14 TSH and the RR of primary outcomes analyzed by Generalized additive models with smoothing splines. (A) The RR of clinical pregnancy peaked at the threshold of 4.5 mIU/L and kept stable thereafter; (B) the RR of live birth peaked at the threshold of 5.5 mIU/L and decreased 30% when D14 TSH increased one unit. (C) The RR of miscarriage remained stable when the D14 TSH levels were less than 6.5 mIU/L and significantly increased 76% when D14 TSH increased one unit. RR: Relative risk; CP, Clinical pregnancy; LB, Live birth; Mis, Miscarriage; D14 TSH, Thyroid stimulating hormone levels 14 days after embryo transfer.
