OR, odds ratio; CI, confidence interval. Age, BMI, energy intake, and occupational exposure were included in the MLR as covariates at first level, and family history of cancer was included at second level (variance 1.637, standard error 0.099, intraclass correlation coefficient 0.33, and median odds ratio 3.38).
