In the sensitivity analysis after excluding values for TNF-α when severe infection was reported, the main effect of mean pregnancy DII (B = 0.093, p = 0.004 unadjusted; B = 0.09, p = 0.014 adjusted), and of the DII*PSS interaction term (B = 0.131, p = 0.02 unadjusted; B = 0.134, p = 0.019 adjusted) on TNF-α remained significant. The gene discussed is TNF; the disease is infection.
