Viral Dynamic Surveillance in COVID-19 Patients: A Cohort Study

Figure 3

Abnormal biological variables were associated with longer viral duration. (a) Kaplan-Meier curve for CD4+ T cell profiles of patients with low and normal level. (b) Kaplan-Meier curve for CD8+ T cell profiles of patients with low and normal level. (c) Kaplan-Meier curve for PLT/LYMPH of patients with low and high ratio. (d) Kaplan-Meier curve for PLT/MONO of patients with low and high ratio. (e) Kaplan-Meier curve for AST profiles of patients with high and normal level. (f) Kaplan-Meier curve for ALT profiles of patients with high and normal level. (g) Multivariate analysis of the experimental parameters using Cox proportional hazards regression models. (h) Kaplan-Meier curve for PI profiles of patients with high and low value. (i) The duration of different viral shedding for aspartate/alanine amino transferase level. (j) Kaplan-Meier curve for AST/ALT ratio profiles of patients with high and normal level. Standard normal value for AST/ALT ratio is [0.8, 1.5].
