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

backgroundChronic obstructive pulmonary disease (COPD) is a progressive disease associated with substantial morbidity and mortality. Acute COPD exacerbations are a primary driver of significant burden and contribute to disease progression.

methodsThis retrospective, observational cohort study used the Optum Clinformatics

resultsOf the 156,462 included patients, the largest proportion of patients (46.6%) were initiated on long-acting beta-agonists/inhaled corticosteroids. The majority of patients progressed to GOLD E over 5 years. The risk of progressing to GOLD E was approximately 3 times higher in the GOLD A/B1 versus GOLD A/B0 group (hazard ratio [HR] 2.92; 95% CI 2.84-3.00; P < 0.001). The strongest predictor of progressing to GOLD E was history of having a moderate exacerbation. Other independent predictors included older age, having Medicare versus commercial insurance, and the presence of Elixhauser comorbidities.

conclusionsDespite use of inhaled maintenance treatments for COPD, most patients still progressed to a frequent or severe exacerbator phenotype. New therapies are needed to modify the disease trajectory in COPD.
