The ‘Grade B' fixed-effect meta-analysis implicated rs1250241 in FN1 on 2q35 (OR (95% CI)=1.23 (1.15–1.30); PGrade B=2.99 × 10−9) and rs74491657 on 7p12.3 (OR (95% CI)=1.46 (1.28–1.59); PGrade B=2.24 × 10−8) as genome-wide significantly associated with endometriosis risk (Table 1). This evidence concerns the gene FN1 and endometriosis.
