1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundPrimary ciliary dyskinesia (PCD) and cystic fibrosis (CF) are muco-obstructive lung diseases that are caused by distinct genetically determined defects in mucociliary clearance; however, knowledge on the relative severity of airway mucus dysfunction and chronic inflammation remains limited. The aim of this study was therefore to compare sputum viscoelastic properties, inflammation markers and the proteome between patients with PCD and patients with CF before and under elexacaftor/tezacaftor/ivacaftor (ETI) therapy.

methodsWe compared sputum rheology, inflammation markers and the proteome in 42 clinically stable adolescent and adult patients with PCD, 40 patients with CF with at least one

resultsThe elastic modulus (

conclusionsClinically stable patients with PCD show changes in sputum viscoelastic properties, inflammation markers and the proteome that are less severe than in patients with CF at baseline, but comparable to CF patients on ETI therapy.
