\title{MeSH Descriptor Frequencies Across PubMed}
\format{
A data.table with 30,521 rows and 4 columns:
\describe{
  \item{DescriptorUI}{MeSH descriptor unique identifier (e.g.,
    \code{D000001})}
  \item{DescriptorName}{Canonical MeSH descriptor name}
  \item{n_pmids}{Number of distinct PubMed records indexed with this
    descriptor}
  \item{prop_total}{Proportion of all 39,703,112 PubMed PMIDs indexed
    with this descriptor}
}
}
\source{
Computed from \code{mesh_descriptor} table in a local PubMed
  PostgreSQL mirror; descriptor metadata from the NLM MeSH Thesaurus
  (April 2026).
}
\usage{
data_mesh_frequencies
}
\description{
Baseline frequencies for MeSH descriptors computed from a local PostgreSQL
mirror of PubMed (April 2026). For each descriptor, counts reflect the
number of distinct PMIDs indexed with that term; proportions use the full
PubMed corpus of 39,703,112 PMIDs as denominator. Descriptor UI and
canonical name are joined from the NLM MeSH thesaurus.
Intended as a baseline for MeSH term enrichment analyses against arbitrary
PubMed subsets.
