The multivariate adjusted association between average albumin (as a continuous variable) and all-cause mortality at the 14th and 28th day is mixed by ARDS(P value of 14th day = 0.0003, P value of 28th day = 0.0092, P value of 90th day = 0.0412) (Table S6). The gene discussed is ALB; the disease is acute respiratory distress syndrome.
