Fig. 3: 28-day case hospitalisation risk and fatality risk over time in people with Covid-19.

A 28-day case hospitalisation risk. B 28-day case fatality risk. Lines represent the probability estimate for each age group and shaded areas represent 95% confidence intervals from mixed effects logistic regression models, adjusted for patient-level covariates, at mean levels of each covariate (N = 2,311,282).
