Blood type and survival rate - In early 2020, medical researchers in China investigated the association between blood type (A, B, AB and O) and
severity of COVID-19 symptoms. The researchers collected information about blood type from patients in Jinyintan hospital in Wuhan, China, in
January 2020. The table below summarizes the information for a sample of 867 patients from this investigation.
