Factors associated with glomerular filtration rate estimating equation accuracy^a in HIV-positive and HIV-negative participants.

<p>eGFR_cr and eGFR_cys are glomerular filtration rates estimated by CKD-EPI equations using plasma creatinine and cystatin C, respectively; mGFR, measured glomerular filtration rate by iohexol clearance.</p>a<p>Accuracy shown as percent of estimated GFR values within 30% of measured GFR values (95% confidence interval).</p>b<p>P values in bold font indicate difference is statistically significant accounting for multiple comparisons (see text).</p>c<p>Medians 8.3% and 3.8% in HIV-positive and HIV-negative groups, respectively.</p>d<p>Medians 30.7% and 10.7% in HIV-positive and HIV-negative groups, respectively.
