For an article or any other scientific work to be published and worthy of recognition, all collected data and results must be amenable to holistic analysis and systematization. Structure and clarity are the primary requirements for Scopus, BAK, and WoS articles. To maximize the professional effectiveness of a study, a meta-analysis is conducted. This is a comprehensive statistical analysis of the results and their heterogeneity, which identifies, examines, and explains the underlying heterogeneity and differences in the study's results. Statistical calculations enhance the usefulness and objectivity of valid conclusions. Any scientific article topic requires high-quality statistical data, which can be achieved using various methods, including criteria processing, statistical analysis of existing heterogeneity in the results, obtaining a generalized estimate of the effect size, and sensitivity analysis of the conclusions.
Variations in meta-analysis methods
Methods differ from the main approaches in their narrow focus. First and foremost, a statistical approach depends on the type of data being analyzed and its effect.
Binary data – calculation of odds ratio, relative (or differential) risk in comparison with samples.
Continuous data is the range of values of the behavior of the object being studied.
For studies with internal variance, the Mantel-Haenszel method is used.
To calculate the OR:
For the criterion of testing the significance of the general measure of connection:
For statistics:
For random effects studies, both within- and between-study variances are summed.
Cumulative meta-analysis – calculation of prior and posterior probabilities.
Bayesian meta-analysis is the calculation of prior probabilities of the effectiveness of interventions, taking into account indirect evidence.
Regression meta-analysis is the process of taking into account the influence of several characteristics of a study on its results.
