Nevertheless, meta-regression factors/covariates should be entered for each study.
CSV data file specifically containing study name, estimate, and standard error (SE) are exported from RevMan. The funnel plot asymmetry evaluation and derivation of Egger or Omnibus P values can be easily derived using JASP ( ). Although RevMan 5 can be used for sensitivity analysis, meta-regression requires a different software. OriginPro ( ) is beneficial to obtain the data from complex formats, such as 2D-image or embedded matrix sheets.

Other software packages that have similar functions include WebPlotDigitizer ( ) or Plot Digitizer ( ). The numerical data obtained are exported and saved as. Using axis point and curve point tools, one can define the graph axis and data set points of an imported image, respectively. In subsequent paragraphs, we report the types and representative examples of software used for data management in meta-analysis.įor data extraction from images, authors can use Engauge digitizer ( ) effectively and reliably to import images from an article directly or via Microsoft Paint. Contrariwise, it is also true that self-learning of additional software by a researcher critically reduces the need for collaborating with a statistician, which in turn might improve the quality of research. Generally, it is believed that clinical researchers often make mistakes when they undertake their own data analysis by not enlisting a statistician before and after undertaking a study. This is because primary software programs are deficient in performing additional analyses, such as meta-regressions and network plotting. Available from ) and Cochrane RevMan calculators ( ), one should be aware of user-friendly auxiliary software to progress in meta-analysis. IBM SPSS Statistics for Windows, IBM Corp., 2017. Available from ), STATA (StataCorp., 2015. R Foundation for Statistical Computing, Austria. Apart from primary statistical software programs, such as SAS (Copyright © SAS Institute Inc., SAS Campus Drive, USA), R (R Core Team, R: A language and environment for statistical computing. The challenge arises when multiple analyses are required, and the researcher needs to choose the correct software program. However, detailed information on additional auxiliary software use is inadequate. In the published literature of high-impact-factor anesthesia journals, we observed that RevMan 5 (Review Manager, ,Version 5.4, The Cochrane Collaboration, 2020) is the most frequently used primary meta-analytical software package. Hence, researchers need additional knowledge regarding software programs used to perform meta-analysis.
