Identify and extract Conflicts of Interest statements in PMC XML files.

Takes a PMC XML file and returns data related to the presence of a Funding statement, including whether a Funding statement exists. If a Funding statement exists, it extracts it.

Usage

rt_register_pmc(filename, remove_ns = FALSE)

Arguments

filename: The name of the PMC XML as a string.
remove_ns: TRUE if an XML namespace exists, else FALSE (default).

Value

A dataframe of results. It returns the unique article identifiers, whether this article was deemed a research, review or systematic review, whether the text was deemed relevant to registration (e.g. contained the word registration), whether a Methods section was identified, whether an NCT number was identified, whether a registration was explicitly identified (defunct), whether a registration statement was found, what the registration statement was, whether it the registration was identified from the PMC XML (i.e. it was found within a dedicated registration tag) and whether each labeling function identified a relevant text or not. The labeling functions are returned to add flexibility in how this package is used; for example, future definitions of Registration may differ from the one we used.

Examples

# \donttest{
# Path to a bundled example PMC XML file.
filepath <- system.file(
  "extdata", "PMID32171256-PMC7071725.xml", package = "rtransparency"
)

# Identify and extract meta-data and indicators of transparency.
results_table <- rt_register_pmc(filepath, remove_ns = TRUE)
# }
