IRS-OLAP: a literature-measurement instrument applied to the COVID-19 and dementia literatures

Instrument, frozen pre-specification, vocabularies, result files, figure and table scripts and verification scripts for a study measuring how the COVID-19 and the dementia literatures state one mechanistic cascade at opposite ends, with a ranked list of under-examined mechanistic links. Contents: the scanner and its code; the hash-locked pre-specification and vocabulary; the full-text census result files; the per-event cascade simulator run; the node-level audit over two corpora indexed with Medical Subject Headings, with its PubMed E-utilities harvest scripts, its 15,247- and 54,716-record files and a verification script; the scripts that draw every figure and build every table; the six result tables as CSV and as one spreadsheet; and the reference library. Raw article XML is not redistributed, for licence and size reasons; every corpus is reconstructable from the deposited query manifests. No manuscript text, no rendered figures and no patient-level or identifiable data are included. Cite the concept DOI 10.5281/zenodo.23161815, which resolves to the current version.
