  1. Positive—Detection of expected DNA product. Negative—Absence of expected DNA product.
  2. a adjusted for M. hyorhinis and Mollicutes. The goodness of the adjustment was evaluated by the Hosmer–Lemeshow test (P = 0.914)
  3. b Considering the case group, n = 73
  4. c Considering n = 113 patients
  5. OR, odds ratio; CI, confidence interval; qPCR, quantitative polymerase chain reaction
