OR and 95% CI for pancreatic cancer associated with antibody levels to Porphyromonas gingivalis ATTC 53978

Antibody level to P gingivalis ATTC 53978Case/controlsOR (95% CI)*MV OR (95% CI)†
Low levels (≤200 ng/ml)376/3971.0 (referent)1.0 (referent)
High levels (>200 ng/ml)29/192.00 (1.00 to 4.00)2.14 (1.05 to 4.36)

 High levels (>200 ng/ml)25/192.10 (0.99 to 4.46)2.11 (0.97 to 4.59)
  • *OR and 95% CI were obtained using conditional logistic regression (cases were matched to controls on centre, sex, follow-up time, age at blood collection, date and time of blood collection, fasting status and use of exogenous hormones among women).

  • †Multivariate ORs (MV OR) were obtained using conditional logistic regression and additionally adjusting for body mass index (continuous) and smoking status (never, past, current).
