Further, among these 13 significant predictors of outcomes, eight had P<0.01 (one-way ANOVA) and P<0.05 (slope significance by linear trend analysis) statistical values, and these eight variables were included in an order multivariate logit regression, and three variables retained in the final model which were statistically significant independent determinants of COVID-19 hospitalization outcome (Table 4), which were albumin, lymphocyte and IL-6. This evidence concerns the gene IL6 and COVID-19.
