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

Background: Managing patients with primary ciliary dyskinesia (PCD) is challenging due to limited therapeutic options and lack of sensitive, disease-specific outcome measures. Hyperpolarised 129-xenon magnetic resonance imaging (Xe MRI) is an emerging imaging modality that quantifies ventilation heterogeneity using the ventilation defect per cent (VDP). In other obstructive lung diseases, VDP has demonstrated increased sensitivity compared to conventional lung function measures; however, its utility in PCD has not been established. In PCD, we aimed to: 1) determine the feasibility of Xe MRI; 2) evaluate the same-day repeatability of VDP; and 3) explore the relationship between VDP with lung clearance index 2.5% (LCI Methods: In this cross-sectional observational study, participants >6 years old with confirmed PCD were recruited from two Canadian PCD centres. Participants underwent lung function testing to measure FEV Results: 16 participants completed the study. In all participants, the VDP was elevated (VDP>2.3) with a median VDP of 11.05% (IQR: 4.83-13.67%). Same-day repeat Xe MRI VDP had an ICC>0.95 and B&A showed good agreement. VDP positively correlated with LCI Conclusions: Xe MRI is a feasible imaging modality to capture lung disease in PCD. VDP has excellent same-day repeatability and correlated strongly with LCI
