Table 2 Unadjusted and adjusted associations between KLRG1+CD8+ T cell groups and ageing parameters in HIV+

From: Immunosenescence of the CD8+ T cell compartment is associated with HIV-infection, but only weakly reflects age-related processes of adipose tissue, metabolism, and muscle in antiretroviral therapy-treated HIV-infected patients and controls

  1. Adjusted analyses are in grey. Age was adjusted for HIV-duration, ART-duration, and current ART; IL-6, suPAR, HOMA-IR, metabolic syndrome, VAT, and lLMI were adjusted for age, HIV-duration, ART-duration, and current ART
  2. Abbreviations: HOMA-IR homeostatic model assessment of insulin resistance, IL-6 interleukin-6, KLRG1 killer cell lectin-like receptor G1, lLMI leg lean mass index, suPAR soluble urokinase plasminogen activator receptor, T N naïve T cell, VAT visceral adipose tissue
  3. The bold values are statistically significant at * P < 0.05
  4. aParameters were transformed using log2(x). Estimates and confidence intervals are back transformed using (2β-1) × 100, and shown as percent change in the outcome per unit increase of the covariate
