Figure 5.

Estimated HRs (solid lines) and 95% CIs (dashed lines) for all-cause mortality associated with levels of moderate aerobic physical activity (MPA)+vigorous aerobic physical activity (VPA). MPA +VPA associations are estimated using cubic splines with three knots. Results are shown stratified by sex. CPH models allow for combinations of age and race to have their own baseline hazard. CPH models control for income, education, marital status, smoking status, BMI, chronic conditions and survey year. HRs and 95% CIs are plotted on a natural log scale. BMI, body mass index; CPH, Cox proportional hazard.
