Multivariate logistic regression analyses.

To adjust the difference in background characteristics among the IOP groups, p values were calculated using multivariate logistic regression analyses to compare the Q1 and the Q2, Q3, and Q4 groups. For calculation of the odds ratios, the Q1 group was the reference. SBP, systolic blood pressure; DBP, diastolic blood pressure; ROM, diacron reactive oxygen metabolites; BAP, biological antioxidant potential; SH, sulfhydryl; OR, odds ratio; CI, confidence interval.
