Development of an excel spreadsheet for metaanalysis of indirect and mixed treatment comparisons | Desarrollo de unahojaexcelparametaanálisis de comparaciones indirectas y mixtas
Metaanalyses in clinical research usually aimed to evaluate treatment efficacy and safety in direct comparison with a unique comparator. Indirect comparisons, using the Bucher's method, can summarize primary data when information from direct comparisons is limited or nonexistent. Mixed comparisons allow combining estimates from direct and indirect comparisons, increasing statistical power. There is a need for simple applications for metaanalysis of indirect and mixed comparisons. These can easily be conducted using a Microsoft Office Excel spreadsheet.We developed a spreadsheet for indirect and mixed effects comparisons of friendly use for clinical researchers interested in systematic reviews, but nonfamiliarized with the use of more advanced statistical packages. The use of the proposed Excel spreadsheet for indirect and mixed comparisons can be of great use in clinical epidemiology to extend the knowledge provided by traditional metaanalysis when evidence from direct comparisons is limited or nonexistent.
