Correlations between the follicular fluid sRAGE protein concentration and other clinical parameters

	Variable	r	P value
FF sRAGE (pg/mL)	Age	0.134	0.417
	BMI	−0.192	0.242
	Days of stimulation	−0.104	0.523
	Total Gn dose	−0.451	0.004
	Oocytes retrieved	−0.037	0.831
	Normal fertilization rate	0.026	0.739
	Number of high-quality embryos	0.119	0.407

Note that Pearson’s or Spearman’s rank correlation coefficients were calculated using the follicular fluid sRAGE levels and each clinical parameter, such as age or BMI. Univariate and multivariate linear regressions were performed to examine the relationships between follicular fluid sRAGE level and total Gn dose, number of days of stimulation, number of oocytes retrieved, and number of high-quality embryos.
