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

backgroundTreatment with Ivacaftor provides a significant clinical benefit in people with cystic fibrosis (PWCF) with the class III G551D-CFTR mutation. This study determined the effect of CFTR modulation with ivacaftor on the lung microbiota in PWCF.

methodsUsing both extended-culture and culture-independent molecular methods, we analysed the lower airway microbiota of 14 PWCF, prior to commencing ivacaftor treatment and at the last available visit within the following year. We determined total bacterial and Pseudomonas aeruginosa densities by both culture and qPCR, assessed ecological parameters and community structure and compared these with biomarkers of inflammation and clinical outcomes.

resultsSignificant improvement in FEV

conclusionsFollowing treatment with ivacaftor, significant improvements in clinical parameters were seen. Despite modest changes in overall microbial community composition, there was a shift towards a bacterial ecology associated with less severe CF lung disease. Furthermore, a significant correlation was observed between richness and diversity and levels of circulating inflammatory markers.
