The variation characteristics of the coefficients of these variables are shown in Figure 3A. Nine prognostic indicators were screened, including age, sex, MPO-DNA, cfDNA, sodium (Na), creatinine (Cr), alanine transaminase (ALT), hepatic encephalopathy (HE), and neutrophil-to-lymphocyte ratio (NLR). The gene discussed is MPO; the disease is hereditary elliptocytosis.
