Description of the Mayo classification of ADPKD [50]

Mayo classification	1A	1B	1C	1D	1E
TKV increase per year, %	<1.5	1.5 – 3	3 – 4.5	4.5 – 6	>6
eGFR slope per year, ml/min/1.73 m2	−0.1	−1.2	−2.5	−3.4	−4.6
Incidence of ESRD at 10 years, %	2.4	11.0	37.8	47.1	66.9

ADPKD = Autosomal dominant polycystic kidney disease; eGFR = estimated glomerular filtration rate; ESRD = end-stage renal disease; TKV = total kidney volume.
