SDNN (log transformed) in the total population by sex and health behaviour: a) by sport activity index, b) by alcohol consumption, c) by currently smoked tobacco products, d) by ever smoked tobacco packyears, e) by dietary pattern index. Bars represent age-adjusted SDNN means (± 95% CI) by categories of health behaviour variables, lines represent loess curves (± pointwise 95% CI), p-values were calculated by χ2-test comparing the deviance between the age-adjusted exposure model and the model without the exposure variable.
