 Combined genotype of oestrogen receptor α polymorphism in controls and patients with systemic lupus erythematosus (SLE). For the combination of the PvuII and XbaI polymorphisms, all combinations of genotypes were observed in SLE patients and the three major combined genotypes: ppxx, Ppxx, and PpXx. SLE patients were less likely to have the ppxx genotype than controls (*pc = 0.032, OR = 0.52 (95% CI, 0.32 to 0.83)). The frequency of the ppXx genotype was significantly higher in the childhood onset SLE subgroup than in the control group or the adult onset subgroup (**pc = 0.0009, OR = 22.80 (3.94 to 170.36) v controls; pc = 0.027, OR = 16.29 (1.83 to 371.63) v adult onset SLE). CI, confidence interval; OR, odds ratio.
