JADA January 2018
The authors assessed whether dentists’ diagnostic inferences differ when test accuracy information is communicated using natural frequencies versus conditional probabilities. A parallel, randomized controlled trial with dentists was carried out in Rio de Janeiro, Brazil. The dentists received a question on the probability of a patient having interproximal caries, given a positive bite-wing radiograph. This question was asked using information that was formulated into either natural frequencies or conditional probabilities.

Key Words: Diagnosis; communication barriers; persuasive communication; health education; risk; probability.
