OR and 95% CI for pancreatic cancer associated with two profiles of antibody response (clusters 1 and 2)

Cluster*Case/ controlsMV OR (95% CI)†
1. Low antibody levels to commensal oral bacteria192/2291.0 (referent)
2. High antibody levels tocommensal oral bacteria212/1870.55 (0.36 to 0.83)
  • *For more details on cluster analysis approach, refer to Supplemental Methods.

  • †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) and adjusting for body mass index and smoking status.
