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

Exacerbations of chronic obstructive pulmonary disease (COPD) lead to substantial morbidity and mortality. Viral infections could be an important cause of acute exacerbations of COPD (AECOPD) and only a few studies report the prevalence of respiratory viruses on this disease. We aimed to update the review on the prevalence of respiratory viral infection in patients with AECOPD with a meta-analysis. We reviewed the prevalence of respiratory viruses on this disease by searching PubMed systematically to identify primary studies published from Jan 1990 to March 2012. Studies met with seven criteria were extracted for meta-analysis. A total of 17 studies were eligible for the meta-analysis. Weighted overall prevalence of respiratory viruses in patients with AECOPD was 39.3% (95% CI 36.9-41.6) with a high degree of a heterogeneity (I (2) > 75%). In contrast, the rate in stable COPD patients from four studies was 13.6% (95% CI 9.0-18.2) without any apparent heterogeneity. Pooled risk ratio for respiratory viral infection was 4.1 (95% CI 2.0-8.5) for AECOPD as compared with stable COPD. Rhinovirus was the most common virus and with a weighted prevalence of 14.8% (95% CI 13.3-16.5). Respiratory viruses probably are important etiological agents in patients with AECOPD as compared with the stable COPD patients. This result would help to provide better strategies for management of AECOPD and health-care planning.
