Each review is analysed in a structured format, starting with the question, a brief background and a summary answer, followed by the results presented in comprehensive and concise way. The authors then illustrate the value that the review adds to the current knowledge, the main methodological limitations of the included studies and finally the implications of the review’s conclusions for future research.
