Table 1 Basic characteristics of the study population. All non-metric parameters are shown as absolute values and by percentages. Continuous variables are expressed as median and range. *: mean ± standard deviation (SD); +median/range; K = potassium, Mg2+ = magnesium, Ca2+ = calcium, Na+ = sodium, TTKG = transtubular potassium gradient, N = number, PSD = potassium-sparing diuretic (eplerenone and spironolactone)
