Logistic regressions between lower leg arterial calcification (dependent variable) and selected independent variables.

Absolute value of z statistics in parentheses.*p**pABI = Ankle Brachial index, F-L = Framingham-Laurier score, LLAC = lower leg arterial calcification, LDL-C = Low density lipoproteins.括号内为z统计量的绝对值。*p < 0.05，**p < 0.01；ABI = 踝臂指数（Ankle Brachial Index），F-L = Framingham-Laurier评分，LLAC = 小腿动脉钙化（lower leg arterial calcification），LDL-C = 低密度脂蛋白（Low density lipoproteins）。
