From: COVID-19 mortality in Italy varies by patient age, sex and pandemic wave
Kaplan–Meier survival curves for the entire Italian series of SARS-CoV-2-positive persons (panels A–C), for non-hospitalized persons (panels D–F), and for hospitalized COVID-19 patients (panels G–I) in the Italian national COVID-19 series, by age group, sex, and pandemic wave (1 = before June 30, 2020, 2 = from July 1 to December 31, 2020, and 3 = after December 31, 2020). Crosses denote censored samples. Numbers of patients at risk for each group, at each time point, are reported under each plot. Log-rank test P < 2 × 10–16, except for panel (E) for which P = 1.2 × 10–11.
