Table 2 Multivariable linear regression analysis for associations of log-mortality and log-prevalence of COVID-19 with the frequency of the Val105 allele in the various countries around the world

From: The morbidity and mortality of COVID-19 are correlated with the Ile105Val glutathione S-transferase P1 polymorphism
