Six patients were excluded from deprivation analysis as postcode unavailable.
*Mean (SD) values eGFR (mL/min/1.73 m2) and median (IQR) of urine protein:creatinine ratio mg/mmol). Six patients were excluded from deprivation analysis.
eGFR, estimated glomerular filtration rate; GPA, granulomatosis polyangiitis; MPA, microscopic polyangiitis; Q1, most deprived; Q5, least deprived.
