Figure 1

Systolic and diastolic blood pressure values before (light boxes) and after (dark boxes) spironolactone commencement. The blood pressure values are described for the entire study population and stratified by a serum potassium level of 4.5 mEq l−1. *P values derived from paired t-test comparisons of blood pressures before and after spironolactone therapy.
