aStudies could span multiple data extraction points (e.g. a study involving infants, children and adolescents); therefore, numbers and percentages reported within each category can exceed the maximum number of studies per study type. Percentages reported as percentage of study type total (animal studies: n = 30, case studies: n = 47, cohort studies: n = 153). N/A information not applicable to study type
