Table 2 Kidney function tests results for patients screened in this study (n = 71)

From: Prevalence of osteo-renal impairment in the Romanian HIV cohort

Characteristic Sub-category n (%) Median (IQR) Percentiles 25, 75 Mean ± SD
Serum urea, mg/dL    N/A N/A 30.2 ± 8.5
Serum creatinine, mg/dL    0.8 (0.3) 0.7, 1.0 N/A
eGFR, mL/min/1.73 sqm    108.4 (34.7) 89.5, 124.2 N/A
eGFR Stage 1 > 90 49 (69.0)    
  Stage 2 60–89.9 21 (29.6)    
  Stage 3 30–59.9 1 (1.4)    
  Stage 4 15–29.9 0 (0)    
  Stage 5 < 15 0 (0)    
Positive proteinuria, n (%)   9 (12.7)    
Renal elastography, kPa    17.1 (11) 12.4, 23.4 N/A
  1. eGFR estimated glomerular filtration rate, IQR interquartile range, N/A not applicable, SD standard deviation
  2. eGFR was calculated by MDRD [7] and is expressed in mL/min/1.73 sqm. Renal stiffness was assessed for 19 patients by one trained operator through shear-waves elastography on Aixplorer (SuperSonic Imagine, Aix-en-Provence, France)
