Reasons for Hospital Admissions in Chronic Hypercapnic COPD Patients on Long-Term Nocturnal Noninvasive Ventilation - A Prospective Observational Study.
Observational study in International journal of chronic obstructive pulmonary disease, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Background: Non-invasive ventilation (NIV) is vital for managing chronic hypercapnic respiratory failure in COPD patients, yet the impact of handling issues like mask compliance triggering hospitalisations is often underestimated. Methods: A prospective, monocentric observational study was performed in COPD patients hospitalized for acute exacerbation with established home NIV therapy. Various questionnaires (CAT, SRI, BORG) and blood gas analysis were used to determine the severity and cause of respiratory insufficiency. Results: 59 patients (mean age 66.57 years ± 9.42, mean BMI 26.99 ± 8.63) were included. 54.24% were female (n=32). The overall cohort had a mean exacerbation rate of 2.24 ± 1.48 within the last 12 months prior to admission. Patients were divided into 4 sub cohorts based on their exacerbation trigger: infection (n=25), handling problem (n=12), non-infection (n=8), and an overlap cohort with evidence of both handling problem and non-handling problem (n=14). Significant differences exist when comparing exacerbation rate (handling-issue cohort: 2.58 ± 1.68 vs infection cohort: 1.76 ± 1.13, p=0.043), total hospital stay (handling-issue cohort: 9.25 ± 5.94 days vs infection cohort: 12.96 ± 5.76 days, p=0.039). There was no significant difference in health-related quality of life measured by the SRI (Summary Score 40.6±12.3 vs 46.8±14.2; p=0.103). Discussion: In our study, we were able to show that handling problems are associated with frequent exacerbations, cause long hospitalisation periods and are associated with a reduced aspects of quality of life. Patient education and training should therefore play a key role in the treatment of patients.
