Tóm tắt	An original research article is the primary vehicle for reporting new empirical findings in a discipline. Following the IMRaD structure (Introduction, Methods, Results, and Discussion), it represents a researcher's novel data, analysis, and interpretation. The journal article format has been the gold standard for scientific communication since the establishment of the Philosophical Transactions of the Royal Society in 1665.	Meta-analysis is the statistical pooling of quantitative findings from multiple independent studies to produce a combined effect estimate. By aggregating data across studies, meta-analysis increases statistical power, reduces random error, and provides a precise summary of an intervention's effectiveness or an association's magnitude. Gene V. Glass coined the term in 1976, formalizing a technique that has become indispensable for evidence synthesis in medicine, psychology, education, and other evidence-based disciplines.
