Univariate logistic regression analyses showed that RPS glomerular lesion (OR 2.60, 95% CI 1.17–5.79, p = 0.019), tubular atrophy/interstitial fibrosis (OR 4.89, 95% CI 2.13–11.20, p < 0.001), interstitial inflammation (OR 5.25, 95% CI 2.03–13.61, p = 0.001), arteriosclerosis (OR 2.55, 95% CI 1.16–5.61, p = 0.021), and arteriolar hyalinosis (OR 6.11, 95% CI 2.65–14.11, p < 0.001) were associated with high-CD4 staining. The gene discussed is CD4; the disease is arteriosclerosis.
