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 leading global health burden that often coexists with other long-term conditions (LTCs). However, the variable prevalence of COPD across LTCs is still under-recognised, which impacts the ability to implement integrated care strategies and targeted case-finding.

objectivesThe aim of this meta-review was to summarise evidence from systematic reviews on the prevalence of COPD in the most prevalent LTCs.

methodsA systematic search of OVID, EMBASE, CINAHL and PubMed was conducted without date restrictions. Only systematic reviews published in English that reported COPD prevalence in LTC populations were included. The ROBIS tool was used to assess the risk of bias. The data extraction tool included author, year of publication, LTC classification, methods used to diagnose COPD, sample size, study settings, shared risk factors, prevalence estimates and odds/risk ratios.

resultsSeventeen systematic reviews met the inclusion criteria. The prevalence of COPD varied across LTCs, ranging from 1.8% in axial spondylarthritis to 40.1% among lung cancer screening populations. Differences in COPD prevalence are likely to be influenced by variation in the LTC populations studied, the study settings and the methods used to identify COPD.

conclusionCOPD is prevalent across LTCs, which emphasises the need for multimorbidity care. The findings indicate that opportunistic COPD case-finding could be of benefit in settings for other LTCs. Standardisation of diagnostic criteria would make the comparability of studies more straightforward.
