ANA positivity wasn't associated with disease severity (p = 0.470), pneumonia severity (p = 0.291), outcome (p = 0.612), or markers of inflammation: CRP (p = 0.151), IL-6 (p = 0.652), ferritin (p = 0.112), SII (p = 0.722). The gene discussed is IL6; the disease is susceptibility to pneumonia measurement.
