↵a Controls were age and sex matched to the non-specific chest pain cases.
↵b Odds ratio estimates and 95% CIs were adjusted by age and sex and consultations in the prior year, using logistic regression.
↵c In 14.9% of controls and 9.7% of patients, smoking status was not recorded.
↵d In 22.2% of controls and 16.8% of cases, body mass index could not be calculated.
↵e In 21.3% of controls and 15.1% of cases, alcohol use was not recorded.
