Missing values were included as a separate category (not shown)

a Odds Ratio (OR) adjusted for age, sex, region, smoking [packyears] and alcohol consumption [g per day]

* To calculate tests for trend, the exposure scores were included as continuous variables in the logistic regression model; (neg.) means: p for trend for a negative association
