Characteristics of the study population.
Fig 1.
Cumulative incidence plot of death and recovery in the total population.
The probability of death conditional on not having recovered after one, two and three weeks of hospital admission was 15.4% (95% 13.1–17.6), 20.5% (95% CI 18.0–23.0), and 22.4% (95% CI 19.8–25.0), respectively. The probability of recovery conditional on not having died after one, two and three weeks of hospital admission was 38.6% (95% CI 35.5–41.6), 54.1% (95% CI 51.0–57.2), and 60.3% (95% CI 57.3–63.3).

Cumulative incidence plot of death and recovery in the total population, separated by age group.
Gray’s test indicated a significant difference between two groups for both death (p<0.001) and recovery (p<0.001). The probability of death for patients aged <70 years after one, two and three weeks of hospital admission was 3.6% (95% CI 2–5.2), 5.4% (95% CI 3.4–7.4), and 6.5% (95% CI 4.3–8.6), respectively, whereas for patients aged ≥70 years, the probability of death was 27.8% (95% CI 23.8–31.8), 36.4% (95% CI 32.1–40.7), and 39.2% (95% CI 34.8–43.5), respectively.

Cumulative incidence plot of death and recovery in the total population, separated by sex.
Gray’s test indicated a statistically significant difference between both groups for recovery (p = 0.003), but not for death (p = 0.050). The probability of death for females after one, two and three weeks of hospital admission was 12.5% (95% CI 10.0–17.1), 17.6% (95% CI 13.7–21.6), and 19.1% (95% CI 15.0–23.2), respectively, whereas for males the probability of death was 16.4% (95% CI 13.5–19.3), 22.1% (95% CI 18.9–25.4), and 24.3% (95% CI 20.9–27.6), respectively.
