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

backgroundBronchiectasis is a respiratory disease structurally characterised by irreversible airway dilatation. Functional impairments are also implicated in bronchiectasis, but the detailed changes in pulmonary function and the impact of clinical factors are yet to be examined. We analysed pulmonary function in patients with bronchiectasis based on their clinical features.

methodsTwo study cohorts-a multicentre bronchiectasis registry and health check-up examinees-were analysed. Airflow limitation was defined as forced expiratory volume in 1 s (FEV

resultsAmong 13 589 health check-up examinees, 606 (4.5%) had bronchiectasis; airflow limitation was more prevalent in those with bronchiectasis than in those without (17.3% vs 8.1%, p<0.001). Ever-smokers with bronchiectasis had the lowest FEV

conclusionsBronchiectasis is an independent risk factor for airflow limitation, and disease severity, smoking and
