An example of the inclusion level of an exon within the COVID-19 infection-associated gene OAS1. A COVID-19 patients in different groups show significantly different PSI levels of OAS1. B Red box shows different PSI level of OAS1. The blue box shows the significantly alternative splicing regions contain SNP site rs10774671 (red arrow pointing down), which was previously reported to be associated with COVID-19 infection and alternative splicing events, indicating CASA is a reliable database
