However, using AAO of BD as a “time to event” variable in a Kaplan-Meier survival curve, we found that the presence of both TLR2 rs3804099 TT risk genotype and low to severe sexual trauma had a cumulative effect on AAO of BD (p = 0.002; pc = 0.02) (Fig. 2). The gene discussed is TLR2; the disease is Behcet disease.
