Moreover, COVID-19 complications such as bacterial coinfection (p < 0.001), anemia (p < 0.001), lymphopenia (p < 0.001), thrombocytopenia (p < 0.001), neutropenia (p = 0.007), high C-reactive protein (CRP) (p < 0.001), and increased lactate dehydrogenase (p < 0.001) negatively influenced survival. The gene discussed is CRP; the disease is anemia (phenotype).
