  1. The proportion of the total number of CAL positive dogs, respectively teeth that are identified by examination of the indicated tooth pairs (sensitivity). Also given for each combination of tooth-pairs is the proportion of test-negative dogs that are truly negative for the presence of CAL ≥1 mm (Negative predictive value).
  2. *Negative predictive value of screen test at dog level.
