Document: However, all of them only include deaths in Wuhan city. This study firstly recruits the largest sample size of death cases from 24 provinces of China and link the direct cause of death with the expression of virus target. Although there have been studies comparing the clinical characteristics of dead and recovered patients and found dead patients were older than recovered patients [7], the risk factors of old deaths had not been identified. We firstly compared the difference of clinical difference between young and old patients and found heart disease was an important risk factor for death of old patients. There were some limitations in our study. The most important one is limited sample size, especially for the stratified analysis. There is a large gap between the sample size of young and old patients, which may cause some findings to be missed. In addition, we may ignore some important information because of the heterogeneity of anonymous COVID-19 data promulgated by local health authorities.
