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

backgroundPseudomonas aeruginosa (PA) isolation in patients with chronic obstructive pulmonary disease (COPD) has been associated with a poor prognosis. This meta-analysis aimed to determine significant risk factors for PA isolation among patients with COPD.

methodsA systematic literature retrieval from PubMed, Embase, Web of Science and China National Knowledge Infrastructure (CNKI) was conducted, including studies from January 2003 to September 2024. Case-control and cohort studies exploring the risk factors for PA isolation in patients with COPD were included in this analysis. A random-effects model was applied to estimate the pooled adjusted odds ratio (paOR) or hazard ratio (paHR) with the corresponding 95% confidence intervals (CI).

resultsThirteen eligible studies with a total of 25,802 participants were included in this meta-analysis. Prior systemic steroid therapy (paOR: 2.67; 95% CI: 1.29-5.53; P = 0.008), previous antibiotic treatment (paOR: 2.83; 95% CI: 1.14-6.97; P = 0.02), high "Body mass index, airflow Obstruction, Dyspnea, Exercise capacity" (BODE) index (paOR: 4.13; 95% CI: 1.67-10.23; P = 0.002), 6-min walking distance (6MWD) < 250 m (paOR: 4.27; 95% CI: 2.59-7.01; P < 0.001), COPD assessment test (CAT) score > 20 points (paOR: 2.49; 95% CI: 1.46-4.23; P = 0.001), hypoproteinemia (paOR: 2.62; 95%CI: 1.32-5.19; P = 0.006), hospitalizations in the previous year (paOR: 3.74; 95%CI: 1.22-11.49; P = 0.021), Bronchiectasis (paOR = 4.81; 95% CI: 3.66-6.33; P < 0.001) and prior PA isolation (paOR: 16.39; 95% CI: 7.65-35.10; P < 0.001) were associated with PA isolation in patients with COPD.

conclusionsOur study identified nine risk factors associated with an increased risk of PA isolation in COPD patients. These findings are significant for the early identification of patients at risk for PA isolation, which might contribute to reducing mortality and improving clinical outcomes.
