CD19 and lymphopenia: The 3rd (OR: 3.76, 95% CI: 1.75–8.0), 4th (OR: 2.26, 95% CI: 1.07–4.76) quartile of CMV IgG, lymphopenia (OR: 2.8, 95% CI: 1.18–6.61), the 1st quartile of CD19+ B cell count (OR: 2.8, 95% CI: 1.24–6.29) still suggested greater risk of unexpected admission, and the 3rd quartile of CD3+ T cell count (OR: 0.19, 95% CI: 0.05–0.71) had a protective effect against mortality.
