Jom kita lihat apa dia meta analisis


Meta-Analysis
Definition
A subset of systematic reviews; a method for systematically combining pertinent qualitative and quantitative study data from several selected studies to develop a single conclusion that has greater statistical power. This conclusion is statistically stronger than the analysis of any single study, due to increased numbers of subjects, greater diversity among subjects, or accumulated effects and results.
Meta-analysis would be used for the following purposes:
  • To establish statistical significance with studies that have conflicting results
  • To develop a more correct estimate of effect magnitude
  • To provide a more complex analysis of harms, safety data, and benefits
  • To examine subgroups with individual numbers that are not statistically significant
If the individual studies utilized randomized controlled trials (RCT), combining several selected RCT results would be the highest-level of evidence on the evidence hierarchy, followed by systematic reviews, which analyze all available studies on a topic.
Advantages
  • Greater statistical power
  • Confirmatory data analysis
  • Greater ability to extrapolate to general population affected
  • Considered an evidence-based resource
Disadvantages

  • Difficult and time consuming to identify appropriate studies
  • Not all studies provide adequate data for inclusion and analysis
  • Requires advanced statistical techniques
  • Heterogeneity of study populations
