Interactions of the associations of socioeconomic status and cardiorespiratory fitness with incident heart failure. (A) Per 1 standard deviation increase in exposures (B) low/high vs. high/low categories of exposures. CI, confidence interval; CRF, cardiorespiratory fitness; HF, heart failure; HR, hazard ratio; SES, socioeconomic status; HRs are adjusted for age, systolic blood pressure, body mass index, heart rate, smoking status, history of type 2 diabetes, history of coronary heart disease, total cholesterol, high‐density lipoprotein cholesterol and physical activity; *, p‐value for interaction
