Indicators (A), classification levels (B) and scoring methods (C) used to classify endemicity and burden of leprosy. The bars represent the number of articles that used a particular indicator, classification level, or scoring method to classify endemicity (red) or burden (blue). An article could mention multiple indicators and classification levels. Other indicators include cure rate (2; endemicity), new cases with dimorphic clinical form (2; endemicity), trend in proportion of new cases with a single lesion at time of diagnosis (1; endemicity), and prevalence/detection ratio (1; burden).
