From: Associations between circulating cell-free mitochondrial DNA, inflammatory markers, and cognitive and physical outcomes in community dwelling older adults

sTNFR1

0.15 (0.07, 0.23)

0.14 (-0.02, 0.29)

TNF⍺

0.51 (0.33, 0.70)

0.61 (0.30, 0.92)

  1. Abbreviations: CI = Confidence interval; CRP = C-Reactive protein; ccf-mtDNA = circulating cell-free mitochondrial DNA; IL-6 = interleukin-6; TNF⍺ = Tumor necrosis factor ⍺; sTNFR1 = soluble Tumor necrosis factor ⍺ receptor 1
  2. Coefficients represent the difference in the outcome per 1000 copies per µL change in the ccf-mtDNA predictor on the log scale. Inflammatory variables were log-transformed. Generalized estimating equations (GEE) were used to estimate the association between ccf-mtDNA and inflammatory markers. Each coefficient was estimated from a separate GEE model. All models adjusted for baseline age, sex, race, and education. Bold indicates p < 0.05
