In the subgroup analyses stratified by LVEF, age, sex, BMI, anemia, renal dysfunction, elevated CRP levels, and the presence of dyslipidemia, there were no significant interactions between the subgroup factors and the effect of high CONUT score relative to low CONUT score for in-hospital all-cause death, except for anemia (Fig. 3). The gene discussed is CRP; the disease is anemia (phenotype).
