Systematic review & meta-analysis
JaeTech has extensive experience with meta-analysis, which is a quantitative, formal, epidemiological study design used to systematically assess the results of previous research in order to draw conclusions about that body of research. Performing a systematic review and meta-analysis involves a rigorous and structured approach that requires a team of researchers with expertise in the relevant subject matter.
Define the research question
JaeTech conduct a systematic review and meta-analysis by using a clearly defined research question or objective. It will guide the search strategy and the inclusion and exclusion criteria for studies.
Develop a search strategy
JaeTech develops a comprehensive search strategy to identify relevant studies by searching multiple databases, such as PubMed, Embase, and Cochrane Library, using a combination of keywords and search terms. The search strategy was documented and reported transparently.
Screening studies
After the search is conducted, the identified studies are screened for inclusion and exclusion criteria. The screening process is carried out by two or more reviewers independently screening the studies and resolving any discrepancies through discussion and consensus.
Extracting data
Once the studies are selected, data is extracted from the studies using a standardized data extraction form. The data was extracted by study characteristics, participant characteristics, interventions, outcomes, and measures of effect size.
Assessing study quality
JaeTech ensures the quality of the included studies by assessing using standardized tools, such as the Cochrane Risk of Bias tool or the Newcastle-Ottawa Scale. The quality assessment helps to determine the strength of evidence and the risk of bias in the studies.
Synthesizing data
The data from the included studies are synthesized using statistical methods to estimate the overall effect size and the level of heterogeneity between the studies. Meta-analysis was performed if the studies are sufficiently homogenous.
Interpreting results
The results are interpreted in light of the research question and the overall quality of the evidence. The results were presented in a narrative summary, tables, and/or forest plots.
