The univariate analysis identified CD38+HLA-DR+ T cells (OR: 1.12, 95% CI: 1.02-1.23, p = 0.016), TC (OR: 0.11, 95% CI: 0.02-0.60, p = 0.010), LDL (OR: 0.06, 95% CI: 0.01-0.53, p = 0.012), and APOB (OR: 0.00, 95% CI: 0.00-0.08, p = 0.008) as being significantly associated with 28-day mortality in COVID-19 patients (Table 1). Here, CD38 is linked to COVID-19.
