Each question should be graded on a scale of 1 to 5 or give an N/A (not applicable) or I/I (insufficient information). Make sure to explain your rating for each question in a sentence or two. ____ 1. Have the researchers clearly formulated their research question or hypothesis? (Explain) ____ 2. Do the researchers explain in detail how they systematically searched for relevant studies? (Explain) ____ 3. Have the researchers clearly identified their criteria for including or excluding the studies produced by the search? (Explain) ____ 4. Are there enough studies included into the final sample for analysis? (Explain) ____ 5. Have the researchers addressed the issue of heterogeneity among the included studies? (Explain) ____ 6. Have the researchers addressed the possibility of bias among the included studies? (Explain) ____ 7. For meta-analysis, are the procedures for data extraction and coding described clearly? (Explain) ____ 8. For meta-analysis, are the numerical results explained in a way that is understandable to a non-specialist? (Explain) ____ 9.

1. Have the researchers clearly formulated their research question or hypothesis? 1 (Explain) The research study does not have an identifiable research question or hypothesis. Normally, a research question should be measurable, specific, realistic, timely, and achievable. The study does not provide a research question with the mentioned qualities but only gives a general overview of the research and only mentions the research objective. 2. Do the researchers explain in detail how they systematically searched for relevant studies? 2 (Explain) There is no mention of the method used to search and obtain the research studies used for analysis. The period for screening is the only bit mentioned, and it is stated to be between January 2008 and August 2015. Through the inclusion and exclusion criteria, the relevant research studies were obtained.
