Multivariable Cox regression analyses of CLBRs.

Independent covariates	HR	95% CI	p-value
PCOS vs tubal	0.95	0.71-1.27	0.732
Age (above 37 vs below 37 years)	0.47	0.39-0.56	<0.001*
AMH (pmol/l)
AMH (7.85-32.13 vs below 7.85)	1.29	0.85-1.96	0.229
AMH (above 32.13 vs below 7.85)	1.72	1.08-2.73	0.023*
AMH (above 32.13 vs 7.85-32.13)	1.34	1.07-1.68	0.010*
BMI (above 24 vs below 24)	1.11	0.97-1.01	0.403
Basal T (above 1.70vs below 1.70)	1.14	0.68-1.92	0.625
Number of oocytes retrieved (above 10 vs below 10)	1.63	1.34-1.98	<0.001*
rLH supplementation vs no rLH	1.01	0.85-1.22	0.686

P-value < 0.05 (asterisk) was considered statistically significant. (CLBRs, cumulative live birth rates; PCOS, Polycystic ovary syndrome; BMI, body mass index; LH, luteinizing hormone; T, testosterone; rLH, recombinant luteinizing hormone; HR, hazard ratio; CI, confidence interval).

The result of the P value is shown in italics.
