claim: immune phenotyping based on neutrophil-to-lymphocyte ratio and igg predicts disease severity and outcome for patients with covid-19
evidence_1: we developed an immune response phenotyping based on nlr and igg that could act as a simple complementary tool to discriminate between severe and nonsevere covid-19 patients and would be helpful in guiding clinical decision.", "immune response phenotyping based on late igg levels and neutrophil-to-lymphocyte ratio (nlr) was characterized to stratify patients with different disease severities and outcome.", "methods anti-sars-cov-2 igg and igm antibodies were determined by chemiluminescence analysis (clia) in covid-19 patients from a single center in wuhan.", 
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  "interpretation covid-19 severity is associated with increased igg response, and an immune response phenotyping based on late igg response and nlr could act as a simple complementary tool to discriminate between severe and nonsevere covid-19 patients, and further predict their clinical outcome.")
