The Prevalence and Risk Factors of Hyperkalemia in the Outpatient Setting

Figure 2

(a) The relationship between serum potassium level and age. The patient’s age had a positive association with serum potassium level (r = 0.220, ). The equation was as follows: Y = 0.010X + 3.788. (b) The relationship between serum potassium level and eGFR. Renal function assessed by eGFR had an inverse association with serum potassium level (r = −0.398, ). The equation was as follows: Y = −0.008X + 4.935. eGFR, estimated glomerular filtration rate.
