The health-evidence.ca registry was used to identify gaps and areas of wealth in the public health review literature. Each of the 21 Focus of Review topic areas were searched, and the quantity and proportion of reviews rated methodologically strong, moderate, and weak were identified. Three categories were used to define availability of reviews within each topic area: (+) few, representing 1-150 reviews; (++) moderate, representing 151-300 reviews; and, (+++) many, representing topic areas possessing greater than 301 reviews. Reviews that addressed multiple topics were accounted for within each topic area that they addressed (e.g., a review on the effectiveness of exercise in preventing chronic disease would be categorized as both physical activity and chronic disease).
