Distribution of eGFR by age and gender in lithium patients and controls. Linear regression lines are shown. eGFR = ml/min. Dots = patients with 1 to 15 years of lithium treatment; diamonds = patients with more than 15 years of lithium treatment (green = 16 to 20 years; orange = 21 to 25 years; red = more than 25 years). eGFR, estimated glomerular filtration rate.
