OR: odd ratio, CI: confidence interval, BMI: body mass index, DIC: ductal invasive carcinoma, LIC: lobular invasive carcinoma, HER2: human epidermal growth factor receptor, and p53: tumor protein 53.
a values were calculated by analysis of variance (ANOVA).
b values were calculated from two-sided chi-square tests or Fisher’s exact tests.
