Virus load and virus shedding of SARS-CoV-2 and their impact on patient outcomes

Figure 3 Factors associated with the duration of viral shedding. A: Changes in cycle threshold values during hospitalization using generalized additive models (F: 46.54, P < 0.0001, adjusted for sex and age); B: From symptom onset to hospital admission (χ²: 85.31, P < 0.0001); C: Cumulative proportions of patients with symptom onset to admission < 7 d, 7-14 d, and > 14 d (χ² = 76.58, P < 0.001); D: Cumulative proportions of patients with PaO₂/FiO₂ < 100, 100-200, > 200 (χ² = 53.74, P < 0.0001) at admission; E: Cumulative proportion of patients with chloroquine or without (P < 0.0001). Ct: Cycle threshold; SARS-Cov-2: Severe acute respiratory syndrome coronavirus 2.
