Mean ± standard deviation. Patients were grouped to four classes based on luminal stenosis and the number of coronary arteries involved. In class 0, luminal stenosis was less than 50% and considered normal. In all other classes, whereluminal stenosis was more than 50%, the participants were considered CAD patients: in class 1, luminal stenosis was more than 50% in one artery; in class 2, luminal stenosis was more than 50% in two arteries; in class 3, luminalstenosis was more than 50% in three arteries. Well collateralization: based on Rentrop scores, patients were categorized into either a poor-collateralization group (grades 0-1) or a well-collateralization group (grades 2-3). Severe vitamin D deficiency: serum 25(OH)D3 level less than 10 ng/mL was considered as severe vitamin D deficiency. |
