- Case–control study of 3568 cases and 35,552 controls. See text for technical description of exposure definitions and covariate adjustment. Conditional results are based on conditional logistic regression which accounts for matching on age and sex. Ordinary results are based on ordinary logistic regression (unconditional), but where sex and age are included as covariates, both in the crude and adjusted analyses
