Table 4 Individual association of cycle parameters with pregnancy rate, clinical pregnancy rate and live birth rate

From: Maximum basal FSH predicts reproductive outcome better than cycle-specific basal FSH levels: waiting for a “better" month conveys limited retrieval benefits

  1. A GEE model controlling for patient and cycle number was constructed to test the association of multiple clinical parameters with pregnancy rate, clinical pregnancy rate or live birth rate. Association was noted as odds ratio (OR) with 95 % confidence intervals. Model significance was noted as ***(p<0.001), **(p<0.01) or *(p<0.05)
