Due to data availability, clinical data of individuals reported by the media and Chinese health authorities were
sought by performing a search on Google. Two searches were performed, one with the search terms
“death”, “pneumonia” and “age” for the clinical data of deceased patients whereas the other with the
search terms “discharge”, “pneumonia” and “age” for the clinical data of surviving patients that served
as controls. The inclusion criteria were (i) elderly patients diagnosed with COVID-19, (ii) exact date of
discharge or death, and (iii) symptoms on admission.
