The current knowledge concerning the association between smoking and risk of rheumatic diseases will be reviewed, especially with regard to rheumatoid arthritis and systemic lupus erythematosus. The role of smoking as a confounder in the context of rheumatic disease will be discussed. What is the magnitude of bias when not adjusting for smoking when investigating associations between smoking-associated exposures and risk of rheumatic disease? Does it suffice to adjust for ever/never smoking when investigating associations between smoking-associated exposures and risk of rheumatic disease? What is the magnitude of residual confounding in comparison with adjusting for cumulative dose of smoking? Questions like these will be answered during the presentation.
