Comparison of the Effects of Diaphragmatic Breathing and Pursed-lip Breathing Exercises on the Sleep Quality of Elderly Patients with Chronic Obstructive Pulmonary Disease (COPD): A Clinical Trial Study.

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: Sleep-related disorders are common among older adults with chronic obstructive pulmonary disease (COPD). Breathing exercises, a key component of pulmonary rehabilitation programs, may improve sleep quality. However, there is a paucity of research on the impact of breathing exercises on sleep quality in elderly patients with COPD. Objective: This study aimed to compare the effects of diaphragmatic breathing (DB) and pursed-lip breathing (PLB) exercises on sleep quality in elderly patients with COPD. Design: Crossover clinical trial. Methods: In this study, 60 elderly patients with COPD were randomly assigned to two groups: DB followed by PLB (Group 1) and PLB followed by DB (Group 2). Each exercise was performed for 4 weeks. Participants completed the Pittsburgh Sleep Quality Index (PSQI), Abbreviated Mental Test Score (AMTS), and COPD Assessment Test (CAT) questionnaires before training. Data were analyzed using descriptive and inferential statistics in SPSS version 21, with a significance level of 0.05. Results: Both DB and PLB exercises significantly improved sleep quality in elderly patients with COPD ( Conclusion: This study demonstrates that DB and PLB exercises enhance sleep quality in elderly patients with COPD. These exercises are recommended as an effective non-pharmacological approach to improve sleep quality in this population.
