Bai Z. et al. demonstrated the predictive value of hemoglobin using the LASSO model, where Hb was found to be significant alongside age, aspartate aminotransferase (AST), lactate dehydrogenase (LDH), white blood cell count (WBC), chronic kidney disease (CKD), and delayed hospital presentation [42]. Here, GSTM1 is linked to chronic kidney disease.
