Mortality risk of COVID-19 in elderly males with comorbidities: a multi-country study
Figure 5. A tree model that shows the proportions of COVID-19 survivors and non-survivors based on three conditions: patient age (<70 or ≥70 years), gender (female, male), and pre-existing comorbidities (yes or no). Scatter plots at the bottom visualize the days from symptom onset to clinical outcomes (death for non-survivors and survival for survivors). Blue and red dots are shown for survivors and non-survivors, respectively. Significant differences in survival time between survivors and non-survivors are indicated by black asterisks.
