Logistic regression analysis of the effect of calcification on periprocedural myocardial infarction in the four groups.

CI indicates confidence interval. Other abbreviations were as followed in Table 2.Age and gender were adjusted in logistic regression analysis in Model 1; age, sex, BMI, hypercholesterolemia, diabetes mellitus, hypertension, smoking, and diseased vessels were adjusted in Model 2.Pa indicates the significance between the S and the C group in a crude Logistic regression analysis; Pb indicates the significance between the M and the C group in a Logistic regression analysis in model 1;Pc indicates the significance between the H and the C group in a Logistic regression analysis in model 2;

CI指置信区间（confidence interval），其余缩写详见表2。模型1的logistic回归分析中校正了年龄与性别；模型2的logistic回归分析中校正了年龄、性别、体质量指数（body mass index，BMI）、高胆固醇血症、糖尿病、高血压、吸烟情况及病变血管数。Pa代表未校正logistic回归分析中S组与C组的组间显著性差异；Pb代表模型1的logistic回归分析中M组与C组的组间显著性差异；Pc代表模型2的logistic回归分析中H组与C组的组间显著性差异。
