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

introductionAcute exacerbations of COPD (AECOPD) often involve mucus hypersecretion. Thus, management of sputum retention is critical. However, the use of airway clearance techniques (ACTs) in people with AECOPD across different healthcare settings and factors influencing their selection remain unclear.

objectiveTo identify and map ACTs used for AECOPD in different healthcare settings and the factors influencing clinical decision-making worldwide.

methodsFour electronic databases and grey literature were searched from 1995 to December 2023, with hand-searching of eligible records. The Joanna Briggs Institute methodology for scoping reviews was followed.

results25 articles were included: 14 clinical studies, five guidelines/statements and six surveys/audits. Clinical studies reported the use of a wide range of single or combined ACTs, with no clear pattern in using particular ACTs in different parts of the world. Recent guidelines advise using ACTs for certain patients with AECOPD, particularly those with hypersecretion, with most guidelines recommending positive expiratory pressure (PEP) therapy. According to surveys, the most used ACTs in Australia and Europe are active cycle of breathing techniques, PEP or forced expiratory technique, while vibrations are most frequently used in Canada. Factors influencing the selection of specific ACTs include the presence of contraindications, level of dyspnoea, access to resources/equipment and ease of learning/performing the technique. All information was derived from hospital settings.

conclusionsThis scoping review identified and mapped ACTs used for people with AECOPD worldwide and their decision-making factors. Future work should focus on community settings.
