  • N is the number of nonmissing values. Percentage (%) values follow the frequencies of the events n for HIV+ AAs and HIV+ non-AAs. P is for the differences between AA and non-AA groups. OI/ADE, opportunistic infection/AIDS-defining event; IDU, intravenous venous use; ACEI/ARB, angiotensin-converting enzyme inhibitor/angiotensin receptor blocker.

  • a The median age at the first valid creatinine measurement.

  • b eGFR calculated using the CKD-EPI equation (10).

  • c ESRD diagnoses at baseline defined by ICD-9 coding.

  • d Absolute CD4 count reported as cells per mm3.

  • e HIV-1 RNA reported as copies per milliliter.

  • f Comorbid conditions at baseline defined by ICD-9 coding.

  • g Pearson test used.

  • h Wilcoxon test used.
