| Objectives | 4 | Provide an explicit statement of the objective(s) or question(s) the review addresses | Introduction, paragraph 6, line 10 |
| Methods |
| Eligibility criteria | 5 | Specify the inclusion and exclusion criteria for the review and how studies were grouped for the syntheses | Methodology, see 2.2 |
| Information sources | 6 | Specify all databases, registers, websites, organizations, reference lists, and other sources searched or consulted to identify studies. Specify the date when each source was last searched or consulted | Methodology, see 2.1 |
| Search strategy | 7 | Present the full search strategies for all databases, registers and websites, including any filters and limits used | Methodology, see 2.1 |
| Selection process | 8 | Specify the methods used to decide whether a study met the inclusion criteria of the review, including how many reviewers screened each record and each report retrieved, whether they worked independently, and if applicable, details of automation tools used in the process | Methodology, see 2.3 |
| Data collection process | 9 | Specify the methods used to collect data from reports, including how many reviewers collected data from each report, whether they worked independently, any processes for obtaining or confirming data from study investigators, and if applicable, details or automation tools used in the process | Methodology, see 2.3 |
| Data items | 10a | List and define all outcomes for which data were sought. Specify whether all results that were compatible with each outcome domain in each study were sought (e.g., for all measures, time points, analyses), and if not, the methods used to decide which results to collect | Methodology, see 2.3 |
| 10b | List and define all other variables for which data were sought (e.g., participant and intervention characteristics, funding sources). Describe any assumptions made about any missing or unclear information | Table 5 |
| Study risk of bias assessment | 11 | Specify the methods used to assess risk of bias in the included studies, including details of the tool(s) used, how many reviewers assessed each study and whether they worked independently, and if applicable, details of automation tools used in the process | Methodology, see 2.4 |
| Effect measures | 12 | Specify for each outcome the effect measure(s) (e.g., risk ratio, mean difference) used in the synthesis or presentation of results | Methodology, see 2.3, line 6. |
| Synthesis methods | 13a | Describe the processes used to decide which studies were eligible for each synthesis (e.g., tabulating the study intervention characteristics and comparing against the planned groups for each synthesis (item #5)) | Methodology, see 2.3, line 4–6. |
| 13b | Describe any methods required to prepare the data for presentation or synthesis, such as handling of missing summary statistics, or data conversions | Involving article exporting from database into mendeley web taught by Mrs. Norizam Salamat |
| 13c | Describe any methods used to tabulate or visually display results of individual studies and syntheses. | Not applicable |
| 13d | Describe any methods used to synthesize results and provide a rationale for the choice(s). If meta-analysis was performed, describe the model(s), method(s) to identify the presence and extent of statistical heterogeneity, and software package(s) used | No statistical analysis was done |
| 13e | Describe any methods used to explore possible causes of heterogeneity among study results (e.g., subgroup analysis, metaregression). | Not applicable |
| 13f | Describe any sensitivity analyses conducted to assess robustness of the synthesized results | Not applicable |
| Reporting bias assessment | 14 | Describe any methods used to assess risk of bias due to missing results in a synthesis (arising from reporting biases). | Not applicable |
| Certainty assessment | 15 | Describe any methods used to assess certainty (or confidence) in the body of evidence for an outcome | Not applicable |
| Results |
| Study selection | 16a | Describe the results of the search and selection process, from the number of records identified in the search to the number of studies included in the review, ideally using a flow diagram (see Figure 1) | Results, paragraph 1 and see Figure 2 |
| 16b | Cite studies that might appear to meet the inclusion criteria, but which were excluded, and explain why they were excluded | Table 3 |
| Study characteristics | 17 | Cite each included study and present its characteristics. | Results, paragraph 2–5 and see Table 4 |
| Risk of bias in studies | 18 | Present assessments of risk of bias for each included study | Results, paragraph 2, line 3, and see Table 4, column 6 |
| Results of individual studies | 19 | For all outcomes, present, for each study: (a) summary statistics for each group (where appropriate) and (b) an effect estimate and its precision (e.g., confidence/credible interval), ideally using structured tables or plots | Results, see Table 4, column 5 |
| Results of syntheses | 20a | For each synthesis, in brief summarize the characteristics and risk of bias among contributing studies | Results, see Table 4, column 2 and 6 |
| 20b | Present results of all statistical syntheses conducted. If meta-analysis was done, present for each the summary estimate and its precision (e.g., confidence/credible interval) and measures of statistical heterogeneity. If comparing groups, describe the direction of the effect | Results, see Table 4, column 5 |
| 20c | Present results of all investigations of possible causes of heterogeneity among study results | Not applicable |
| 20d | Present results of all sensitivity analyses conducted to assess the robustness of the synthesized results | Not applicable |
