11–50% of reproducible results [29–31]. We also found that the
findings from recent literature reviews on miRNAs were discrepant
(Table1). Therefore, this meta-analysis method would fill this gap
to identify consistently dysregulated miRNAs in T2D.
2 Materials
- Statistical software R (https://www.r-project.org) and RStudio
(https://www.rstudio.com). - Installation ofmetaforpackage in R environment.
- An example dataset with dysregulated miRNAs (Additional file
data.csv).
2.1 Instructions R could be downloaded and installed fromhttps://www.r-project.
organd RStudio could be downloaded fromhttps://www.rstudio.
com. In RStudio we can installmetatorpackage [37](seeNote 1).
