Measure Description: Participants were stratified by IMDC risk group using the following criteria: baseline Karnofsky Performance Status <80%; interval between initial diagnosis of renal cell carcinoma to start of first-line systemic treatment for advanced disease <1year; baseline hemoglobin <lower limit of normal (LLN); baseline platelet count >upper limit of normal (ULN); baseline corrected calcium1 >ULN; and baseline neutrophil >ULN. The category was determined by totaling the risk factors per participant and scored as favorable (no factors); intermediate (1 or 2 factors); and poor (≥3 factors).
