In the multivariate model a cluster variance estimator was used to adjust the standard error for three clusters (hospitals). The multivariate model included all clinically relevant co-variates (age >40 years, male sex, CD4 count ≤100 cells/mm3, self-reported cough, being unable to walk unaided, and being admitted during the COVID-19 pandemic).
