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

introductionLumacaftor/ivacaftor (lum/iva) was introduced in the Netherlands in 2017. We investigated 1-year efficacy of lum/iva on lung function and small airway and structural lung disease evaluated by multiple breath nitrogen washout and CT scan. Additionally, we investigated effects of lum/iva on exacerbations, anthropometry, sweat chloride and safety in children with CF in the Netherlands.

methodsChildren with CF aged 6-18 years and homozygous for F508del treated in one of the seven Dutch CF centers for at least 12 months were eligible. Data were extracted from the Dutch CF Registry and electronic patient records. Primary outcome was change in percent predicted FEV

resultsNationwide, 247 children with CF were eligible for lum/iva. Eight patients discontinued lum/iva due to side effects. In total, 223/247 children (90.3%) were evaluated. Mean (range) age at baseline was 11.0 (6.0-17.1) years. There was no change in FEV

conclusionLum/iva was generally well tolerated in a real-life, nationwide pediatric cohort. The efficacy of lum/iva was comparable to phase 3 studies in children. LCI and BA analysis as markers of small airway and structural lung disease showed significant improvement which indicates the importance of these parameters to evaluate treatment effects of CF modulators in children.
