Factors associated with glomerular filtration rate estimating equation accuracya 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.aAccuracy shown as percent of estimated GFR values within 30% of measured GFR values (95% confidence interval).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.
