Lung clearance index response in patients with CF with class III CFTR mutations
Bibliographic record
Abstract
Ivacaftor (KALYDECO) is a cystic fibrosis transmembrane conductance regulator (CFTR) potentiator that increases transmembrane chloride flux in vitro and leads to significant benefits in patients with cystic fibrosis (CF) with class III gating mutations.1–5 Ivacaftor is associated with sustained improvement in FEV1 and weight as well as reduced time to next pulmonary exacerbation.5–7 It has also been shown that 4 weeks of ivacaftor improves the lung clearance index (LCI) in patients with CF with preserved lung function.8 It is presently unclear whether LCI, a measure of ventilation inhomogeneity, provides additional information among patients with more impaired lung function as well as whether the sustained effectiveness of ivacaftor as demonstrated by improvements in the previously mentioned outcomes is also evident in the LCI response. The aim of this observational study was to assess the LCI before and after initiation of ivacaftor treatment over 6 months in patients with CF with a wider range of …

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
