The low-grade inflammation (LGI) score, a novel indicator of chronic LGI, combines C-reactive protein (CRP), leukocyte counts, the neutrophil/lymphocyte ratio (NLR), and the platelet (PLT) count to predict outcomes of patients with various conditions, such as cardiovascular diseases [23], cancers [24], and neurodegenerative diseases [25]. This evidence concerns the gene CRP and neurodegenerative disease.
