Correlation analysis between FF SDF-1α and MIP-1β levels and clinical and laboratory parameters in PCOS patients with a normal BMI. (A) Correlation of SDF-1α levels in follicular fluid with the serum FSH levels as determined by Pearson’s rank test (P = 0.005, r = −0.67, FDR = 0.070). (B) Correlation of MIP-1β levels in follicular fluid with D3 high-quality embryos as determined by Pearson’s rank test (P = 0.006, r = −0.65, FDR = 0.042). (C) Correlation of MIP-1β levels in follicular fluid with D3 good-quality embryo rate (%) as determined by Spearman’s rank test (P = 0.029, r = −0.55, FDR = 0.135). (D) Correlation of MIP-1β levels in follicular fluid with high-quality blastocyst rate (%) as determined by Spearman’s rank test (P = 0.003, r = −0.72, FDR = 0.042). Data represent a statistically significant difference (FDR<0.05)
