Age at ESRD onset as a function of baseline patient characteristics: eGFR (60–110 mL/min/1.73 m2); age (25–45 years); TKV (1000–2000 mL). Midline represents median; upper and lower hinges represent 25th and 75th percentiles; upper and lower whiskers represent highest and lowest values within 1.5 times the interquartile range; data beyond the whiskers are plotted as outliers. eGFR: estimated glomerular filtration rate; ESRD: end-stage renal disease; TKV: total kidney volume
