Focus of tuberculosis systematic reviews.

aDenominator N = 141 represents the total number of research focuses identified by all the included reviews. In this case N is greater than the 137 number of included systematic reviews because some reviews had a research focus captured by more than one category.bCategories 5 and 6 of Table 1 were merged. Note: Cells do not equal 100% because the subdivisions “Other” in “Prevention of diseases and conditions”, “Detection, screening, and diagnosis”, and “Development and evaluation of treatments” were omitted. There was no SR on “Underpinning research” and “Health and social services research.”
