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

backgroundPulmonary function tests (PFTs) and medical imaging in cystic fibrosis (CF) occasionally show discrepancies in severity levels, potentially due to different postures during testing (seated PFTs and supine imaging). To assess this, we utilised multiple breath washout with Short extension (MBW

methodsTwenty three CF patients performed two seated and at least 1onesupine MBW, along with same day OE-MRI. MBW

resultsWe demonstrated a significant increase in LCI

conclusionWe found significant postural differences in MBW
