Chapter 26: Studying the Epidemiology of Temporomanibular Disorders: Recency of Pain
        

Imagine you are conducting a population-based survey of TMD in a population of 2500 people. Of these, 2000 experience no TMD pain between January 1 and June 30 (Pattern F) and 100 people each experience TMD pain that follows the temporal patterns A-E shown below. For the sake of simplicity, assume that surveys of the entire population could be conducted on a single day.

Graphic depiction of a population-based survey of TMD in a population of 2500 people. Of these, 2000 experience no TMD pain between January 1 and June 30 (Pattern F) and 100 people each experience TMD pain that follows the temporal patterns A-E shown below. For the sake of simplicity, assume that surveys of the entire population could be conducted on a single day. All patterns show no pain on January 1. Patterns A, C, E and F show no pain on March 31, while patterns B and D show pain on March 31. Patterns A, C, D, E and F show no pain on June 30
