If you are not familiar with R, you can access the core features of this package on your web browser on its dedicated website.
The metaumbrella package offers several facilities to
assist in data analysis when performing an umbrella review. This package
is built around three core functions which aim to facilitate (i) the
completion of the statistical analyses required for an umbrella review
(via the umbrella() function), (ii) the stratification of
the evidence (via the add.evidence() function) and (iii)
the graphical presentation of the results (via the forest()
function).
First, the umbrella() function automatically performs
meta-analyses and additional calculations needed for an umbrella review.
It outputs an object of class umbrella. The advantage of this function
over standard R packages only designed for fitting a single
meta-analysis lies, for example, in the possibility of automatically
fitting several meta-analyses when input information differs,
automatically extracting the necessary information to stratify the
evidence, and automatically performing the additional tests needed (a
test for excess significance bias, a test for publication bias and a
jackknife leave-one-out analysis).
Second, the add.evidence() function stratifies the
evidence generated by the umbrella() function according to a set of
pre-specified classifications (the classification proposed by
Prof. Ioannidis or an algorithmic version of GRADE classification), or
according to a personalized classification that the users may specify
manually. This feature allows users to rely on already developed
criteria or to develop new ones that match the specific needs of an
umbrella review.
Third, the forest() function creates graphical
representations of the results of an umbrella review, including a forest
plot along with information on the stratification of evidence.
