2. Create a three-level variable ‘alc’ for alcohol consumption using the following categories: light (<0.5 drinks/week), moderate (≥0.5 and <2 drinks/week) and heavy (≥2 drinks/week). Code each category as 0, 1 and 2, respectively for future questions. How many participants are in each category? Alc Number 0 4052 1 2244 2 2900 3.In each level of alcohol consumption (ie, “ALC” variable), what percentage of participants dies over the follow-up period? 4. Run a univariate logistic regression model with death as the outcome and “ALC” as the predictor. Use ALC=0 as the reference group. Interpret the odds ratios for the “ALC” variables. An individual consuming ≥0.5 and <2 drinks/week has 0.693 the odds of death compared to an individual consuming <0.5 drinks/week, over the study period. An individual consuming ≥2 drinks/week has 0.744 the odds of death compared to an individual consuming <0.5 drinks/week, over the study period.
