claim: gut microbiota composition reduces disease severity and dysfunctional immune responses in patients with covid-19.
evidence_1: conclusion associations between gut microbiota composition, levels of cytokines and inflammatory markers in patients with covid-19 suggest that the gut microbiome is involved in the magnitude of covid-19 severity possibly via modulating host immune responses.", "nevertheless, this survey of gut microbiota alterations in association with immune dysregulation revealed that gut microorganisms are likely involved in the modulation of host inflammatory responses in covid-19.", "conclusion: associations between gut microbiota composition, levels of cytokines and inflammatory markers in patients with covid-19 suggest that the gut microbiome is involved in the magnitude of covid-19 severity possibly via modulating host immune responses.", 
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  "they hypothesized gut microbiota would be associated with host inflammatory immune responses in covid-19.", "composition of the gut microbiota in patients with covid-19 is concordant with disease severity and magnitude of plasma concentrations of several inflammatory cytokines, chemokines and blood markers of tissue damage.")
