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

backgroundBreathlessness is a debilitating symptom affecting many adults, yet its prevalence and correlates are not well summarised. This review synthesised evidence on breathlessness prevalence, correlates and assessment methods across general and clinical populations.

methodsWe undertook an umbrella review and updated systematic review using a comprehensive search of three databases up to January 2025. The umbrella review incorporated existing systematic reviews and meta-analyses, while the updated systematic review and meta-analysis included original studies published after the most recent eligible review.

resultsThe umbrella review encompassed 10 reviews conducted between 2010 and 2025, incorporating 315 studies. The primary tool for assessing self-reported breathlessness was the Medical Research Council questionnaire and its modified version (mMRC). The prevalence of breathlessness ranged from 0.9% to 61.6% in general populations and from 20.4% to 87% in clinical populations. Six categories of breathlessness correlates were identified: sociodemographic, physiological, clinical, psychological, environmental and radiological/pathological factors. An updated systematic review and meta-analysis found 15 studies published between 2021 and 2024 reporting prevalence of breathlessness. Using the most common criterion of an mMRC score ≥2, the pooled prevalence was 12.5% (range 3.7-29.5%) in general populations and 37.5% (range 27.5-48.6%) in clinical populations. These studies reported diverse correlates of breathlessness, including psychological and clinical factors. DISCUSSION: Substantial variability exists in the prevalence and correlates of breathlessness, emphasising its complexity and multifaceted nature. This review highlights the need for standardised assessment of breathlessness to assess prevalence and comprehensive approaches to address its diverse factors.
