Get the selected dataset
Description
Retrieving a dataset with study-level aggregate clinical and methodological characteristics (that may act as effect modifiers) extracted from the selected systematic review of the database.
Usage
get.dataset(pmid, show.index = FALSE, show.type = FALSE)
Arguments
pmid |
A scalar with the PMID number of the systematic review found in the database. |
show.index |
Logical to indicate whether to return a data-frame with the
full name of the abbreviated characteristics. The default is
|
show.type |
Logical to indicate whether to return a data-frame with the
type (Demographic, Clinical, Methodological) and subtype (Age, Ethnicity,
Intervention, Outcome, Participant, Risk of bias, Sex, Study design, Study
setting, Withdrawals) of the characteristics. The default is |
Details
The selected dataset refers to a connected network for a specific outcome
studied in the corresponding systematic review.
The R package nmadb was
used to retrieve the corresponding dataset. Specifically, the function
readByID was employed to download the dataset
in the long format. Then, the function
pairwise of the R package
netmeta was implemented
to convert the dataset into wide format with each row repeated as many
times as the number of possible comparisons made in the corresponding
study. The study names (or references) and treatment comparisons, as
returned by readByID, were used to locate the
studies in the corresponding report of the systematic review (and Appendix,
if available) and extract the characteristics available in the relevant
table(s). Each characteristic occupies one column in the dataset.
Characteristics pertaining to intervention features occupied one column for
the experimental and another for the control treatment in the corresponding
comparison.
Value
get.dataset returns the following:
Dataset |
A data-frame (tibble style) with rows referring to the studies and columns to the study-level aggregate characteristics as extracted from the report of the corresponding systematic review. |
Characteristics_index |
A data-frame (tibble style) with the rows
referring to the extracted characteristics (abbreviated name) and columns
to the their full name (if |
