Factors associated with glomerular filtration rate equation biasa in HIV-positive and HIV-negative participants.

eGFRcr and eGFRcys are glomerular filtration rates estimated by CKD-EPI equations using plasma creatinine and cystatin C, respectively; mGFR, measured glomerular filtration rate by iohexol clearance.aBias defined as median difference between estimated glomerular filtration rate (GFR) and measured GFR (25th percentile, 75th percentile).bP values in bold font indicate difference is statistically significant accounting for multiple comparisons (see text).cMedians 8.3% and 3.8% in HIV-positive and HIV-negative groups, respectively.dMedians 30.7% and 10.7% in HIV-positive and HIV-negative groups, respectively.
