Where the Cost of Endometriosis Falls: Europe-wide cost-of-illness model - code, data layer, outputs, parameters and CHEERS 2022 checklist

Companion deposit to the review article Where the Cost of Endometriosis Falls: Diagnostic Delay, Treatment and Productivity Loss - A Review with a Europe-Wide Burden Estimate. The deposit contains everything needed to reproduce the modelled numbers in the article without contacting the authors: the prevalence-based cost-of-illness model for 31 European countries (Python, numpy only), the archived World Bank World Development Indicators data layer it reads, the currency-harmonisation script, the figure scripts, all model outputs including every scenario, and a PDF with the CHEERS 2022 checklist, the parameter table with ranges and provenance, and the annotated model code. Running python model/euro_model_listing.py on these files reproduced the three output files byte for byte on 28 October 2026. The research plan was registered retrospectively on OSF Registries after the study was completed (https://doi.org/10.17605/OSF.IO/8PZTG). That registration documents the plan as executed; it cannot demonstrate pre-specification. Corresponding authors: Viktor Gulyás-Oldal ([e-mail]), Sándor Nagy ([e-mail]) and Károly Szili ([e-mail]).
