Prospective observational study

Medical records

9651

Assessed the case fatality risk (CFR) among COVID-19 patients detected in mainland China, stratified by clinical category and age group.

The median age of the cases outside Hubei was 45 years (range, four days-97 years), and 51% (4,956/9,651) were male. Those who died were significantly older than discharged cases (median age: 77 vs 39 years, p<0.001). 77% (48/62) of deaths occurred in the older adults aged 65 years or above, and 58% (36/62) were male. Multivariate logistic analysis revealed that increasing age, being male, and living in less developed economic regions (e.g. Central region or West and Northeast region) were risk factors for mortality.
