Linear regression analysis also revealed that age (95% confidence interval [CI]: −0.475 to −0.136, P < .001), presence of MetS (95% CI: 0.218–1.123, P = .004), and CRP (95% CI: 0.080–1.297, P = .027) independently influenced intraocular pressure (Table 3). This evidence concerns the gene CRP and metabolic syndrome.
