# Spirometry data (Pulmonary Task Force)

Data location:

`/finngen/library-red/task_force_data/Pulmonary/Spirometry/spiro.tar`

Files included in the tar file:

* `finngen_spirometry_R13.txt` — Main data file (one row per test)
* `finngen_spirometry_R13_rspiro_vals.txt` — Includes GLI predicted values
* `finngen_spirometry_R13_summary.txt` — Per-individual summary
* `spirometryR13.Rmd` / `spirometryR13.html`— Full documentation
* `spirometryR13_slides.pptx` — Overview presentation

Current data (v1.0, released to Sandbox in Dec 2025) contains 123,113 measurements from 46,230 individuals. The data includes pre- and post-bronchodilator values, GLI-2012 predicted values (precent predicted, z-scores, LLN).

Dataset highlights:

* Longitudinal data available for 48% of individuals (≥2 tests)
* 73% of tests include reversibility (bronchodilator response) testing
* GLI-2012 reference values calculated using the rspiro R package

Data has been obtained from the following biobanks: Helsinki Biobank, Auria Biobank, Biobank of Eastern Finland, Borealis Biobank (Northern Finland), Central Finland Biobank and Finnish Clinical Biobank Tampere.
