Forest plots showing odds ratios (OR) and corresponding 95% confidence intervals for the association between plasma COL1α1 levels and coronary atherosclerosis unadjusted (model 1); adjusted for sex, waist-hip ratio, fasting glucose, high density lipoprotein cholesterol, triglycerides (model 2); and for sex, waist hip ratio, age, smoking, the usage of antihypertensive and lipid-lowering medications, diabetes, HbA1c and CRP (model 3). COL1α1 levels were analyzed logarithmized with the base of 2. * Indicates remaining statistical significance (p < 0.05). CACS = coronary artery calcium score; SIS = segmental involvement score; COL1α1 = type I collagen pro-a1 chain; CRP = C-reactive protein.
