boostmtree (version 1.5.1)

spirometry: Spirometry Data

Description

Data consists of 9471 longitudinal evaluations of forced 1-second expiratory volume (FEV1-percentage of predicted) after lung transplant from 509 patients who underwent lung transplant (LTx) at the Cleveland Clinic. Twenty three patient/procedure variables were collected at the time of the transplant. The major objectives are to evaluate the temporal trend of FEV1 after LTx, and to identify factors associated with post-LTx FEV1 and assessing the differences in the trends after Single LTx versus Double LTx.

Arguments

Format

A list containing four elements:

  1. The 23 patient variables (features).

  2. Time points (time).

  3. Unique patient identifier (id).

  4. FEV1-outcomes (y).
