Granular posterior pharyngeal wall
Granular posterior pharyngeal wall is defined as irregular pinkish to reddish nodules at the posterior pharyngeal wall above the level of epiglottis. It was graded as Grade 1 (patchy): multiple nodules surrounded by normal mucosa and Grade 2 (diffuse): multiple nodules without surrounding normal mucosa (Figure 4). If there were both patchy and diffuse areas within the same participant, the Grade 2 was used.
