CRP and incontinentia pigmenti: Logistic regression analysis identified corticosteroid therapy (odds ratio 35.75, 95% confidence interval 1.267–1026, P = 0.039) and a past history of AE-IP (odds ratio 36.25, 95% confidence interval 1.285–1040, P = 0.038) to be significant predictors of AE-IP after pulmonary surgery and serum CRP (odds ratio 1.187, 95% confidence interval 1.073–1.345, P = 0.002) to be the only predictor of AE-IP after non-pulmonary surgery.
