Scattergram showing the relationship between plasma aldosterone (transformed as a logarithm owing to its skewed distribution) and left ventricular mass indexed for body surface area in hypertensive patients with chronic kidney disease (CKD). Circles represent stage I CKD patients; squares represent stage II CKD patients; diamonds represent stage III CKD patients. Dashed hyperbolic lines represent the 95% confidence bands around the regression line.
