Source-locked RStudio reproducibility package for a cetirizine-centered evidence-to-decision reanalysis in seasonal allergic rhinitis

This record contains the source-locked RStudio reproducibility package for a cetirizine-centered evidence-to-decision and approximate standard-information value-of-information reanalysis of oral H1-antihistamines in seasonal allergic rhinitis. The package starts from locked published network meta-analysis outputs and regenerates downstream decision quantities, sensitivity outputs, R-generated figures, validation logs, warning logs, R session information, and SHA256 manifest. It does not update the literature search, modify eligibility criteria, screen additional records, extract new trial data, reconstruct the evidence network, or re-estimate source network meta-analysis treatment effects. The archive includes locked input CSV files, R scripts, recomputed outputs, sensitivity results, figures, quality-control files, manifest, and reproducibility instructions. It does not contain individual participant data. The intended use of this record is computational reproducibility and source-to-decision auditability of the downstream reanalysis.
