95% CI in brackets.B: Coefficient of logistic regression.S.E: Standard Error.Naglekerke R square = 0.53; 0 = No IA during all their life; 1 = IA during all their life.

括号内为95%置信区间（95% Confidence Interval）。B为逻辑回归系数（logistic regression coefficient），S.E为标准误（Standard Error）。内格尔克尔克R方（Nagelkerke R-squared）值为0.53；其中0代表终生未出现IA，1代表终生出现IA。
