Stratified analyses by potential modifiers of the associations between cooking oil and survival.
Note: a For lifestyle, a participant would be defined as “unhealthy” with meeting at least 2 of 3 following criterions, including current smoking (yes), current drinking (yes), and current regular exercise (no); otherwise, he/she was defined as “healthy”. b If a participant was with any comorbidity as shown in Table 1, he/she was defined as “yes”; otherwise, he/she was defined as “no”. c If a participant was with any comorbidity (i.e., hypertension, heart disease, and cerebrovascular disease), he/she was defined as “yes”; otherwise, he/she was defined as “no”. d Overweight and obesity was defined as a BMI ≥ 24.0 kg/m2 according to guidelines for a Chinese population. e Central obesity was defined as a waist circumference ≥ 90 cm in men or ≥85 cm in women. Each stratification adjusted for all factors (sex, age, education, marital status, residence, economic income, co-residence, current smoking, current drinking, current regular exercise, regular intake of foods, comorbidities, BMI, waist circumference, and ADL disability) except the stratification factor itself. The present results were obtained from imputed data set 1, and results obtained from imputations 2 to 5 were similar (data not shown). Abbreviations: ADL = activities of daily living, BMI = body mass index, CI = confidence interval, CVD = cardiovascular disease, TR = time ratio.
