An additional sensitivity analysis excluding patients with prior autoimmune disease did neither differ substantially from the described results: 53.8% vs 28.1% positive ANA titers in participants with persistent vs those with non-persistent symptoms, respectively (p=0.07) and aHR (95% CI) of 3.31 (0.81-13.55), p=0.096. The gene discussed is BTG3; the disease is autoimmune disease.
