Logistic regression analyses of the target variable “presence of aortic atherosclerosis”. First model: Superficial caries and pulpal caries are grouped together as one parameter. Second model: Superficial caries and pulpal caries are separated parameters. N = 248 (both models), Nagelkerke's R² = 0.677 (first model) and 0.644 (second model). Pulpal caries appears in the models only if superficial caries is removed (model not shown).
