Table 1 also shows the baseline characteristics for all participants (n = 643) and separately for those classified as euthyroid (n = 534). At baseline, biochemical thyroid status (including euthyroid, subclinical, and overt hypo- and hyper-thyroidism) was associated with years in education (χ2 = 10.86; df = 4; P = .028), medical history of ischemic heart disease (χ2 = 9.27; df = 2; P < .001), serum albumin (F = 4.33; df = 2; P = .014), CRP (F = 5.06; df = 2; P = .007) and disability score (χ2 = 7.29; df = 2; P = .03) (Supplemental Table 1). This evidence concerns the gene CRP and coronary artery disorder.
