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

Neutrophilic inflammation is characteristic of chronic obstructive pulmonary disease (COPD); yet, there are no effective antiinflammatory therapies. The PDE4 inhibitor roflumilast is approved for use in COPD and suppresses sputum neutrophilia. The mechanism underlying this observation is unclear; therefore, this study addressed whether roflumilast directly affected neutrophil migration. Blood-derived neutrophils were isolated from nonsmokers, smokers, and patients with COPD, and chemotaxis was measured using Boyden chambers. Intracellular calcium ion concentration was measured by fluorimetry, and shape change and CD11b expression were measured by flow cytometry. Neutrophils from patients with COPD showed enhanced chemotactic responses toward both CXCL1 and leukotriene B
