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.

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.

Abstract

backgroundChronic obstructive lung disease (COPD) exacerbations are a significant cause of morbidity and mortality. Data regarding factors which causes or prevents exacerbations is very limited. The aim of this systematic review is to summarize the results from available studies to identify potential risk factors for hospital admission and/or re-admission among patients experiencing COPD exacerbations.

methodsWe undertook a systematic review of the literature. Potential studies were identified by searching the electronic databases: PubMed, EMBASE, BIOSIS, CINAHL, PsycINFO, Cochrane library, reference lists in trial reports, and other relevant articles.

resultsSeventeen articles that met the predefined inclusioncriteria were identified. Heterogeneity of study designs, risk factors and outcomes restrict the result to only a systematic review and precluded a formal meta-analysis. In this review, three predictive factors: previous hospital admission, dyspnea and oral corticosteroids were all found to be significant risk factors of readmissions and variables including using long term oxygen therapy, having low health status or poor health related quality of life and not having routine physical activity were all associated with an increased risk of both admission and readmission to hospital.

conclusionsThere are a number of potential modifiable factors that are independently associated with a higher risk of COPD exacerbation requiring admission/readmission to the hospital. Identifying these factors and the development of targeted interventions could potentially reduce the number and severity of such exacerbations.
