In one paragraph

Review in Journal of thoracic disease, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04694430 (A Integration of Respiratory Medicine and Prevention Multi-center Study to Determine the Prevalence and Influence of Pertussis on Chronic Obstructive Pulmonary Disease Exacerbation in Shenzhen by National Respiratory Diseases Clinical Medicine Research Center), which is not on this map. Cited by 11 papers, 2 of them syntheses that pooled it.

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.

Abstract

Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease. Various classification systems and phenotypes have been proposed. This review highlights the current classifications of COPD, describes the major phenotypes and provides a blue print for risk assessment of COPD. It is likely that more phenotypes and endotypes of COPD will be described paving the way to personalized medicine for patients with COPD.
