Figure 1.

Functional form of serum potassium as a continuous variable with all-cause mortality in a pooled cohort of MESA and CHS participants. The upper figure presents the hazard ratios and 95% confidence intervals (95% CIs) for associations between milliequivalent per liter of serum potassium and all-cause mortality, adjusted for age, sex, race, time-varying eGFR, diabetes mellitus, systolic BP, study cohort (MESA versus CHS), current smoking, pack-years smoking, ever having cancer, angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers, diuretics (potassium sparing and all others), nonsteroidal anti-inflammatory drugs, potassium supplements, β blockers, β agonists, and other antihypertensive medications. The lower histogram presents the distribution of serum potassium concentrations in milliequivalent per liter for 9651 combined individuals from the MESA and CHS. CHS, Cardiovascular Health Study; MESA, Multi-Ethnic Study of Atherosclerosis.
