The Effectiveness of Respiratory Muscle Training on the Duration and Severity of Respiratory Symptoms in Patients With Chronic Obstructive Pulmonary Disease: A Systematic Review and Meta-Analysis.

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
Objective: To evaluate the effectiveness of respiratory muscle training (RMT) on respiratory symptom severity and symptom duration in adults with chronic obstructive pulmonary disease (COPD) and to appraise the certainty of the evidence. Methods: We searched seven databases and included parallel-group randomized controlled trials (RCTs) comparing RMT plus guideline-based care versus control. Meta-analyses were conducted in RevMan using fixed- or random-effects models as appropriate. Risk of bias was assessed using RoB 2. Certainty of evidence was assessed using the GRADE approach. Because multiple outcomes were analysed, we controlled the false discovery rate using the Benjamini-Hochberg (BH) procedure across prespecified meta-analysed outcomes and report both unadjusted and BH-adjusted Results: Seven RCTs ( Conclusion: In adults with COPD, adding RMT to guideline-based care probably reduces dyspnoea and improves health-related quality of life (moderate certainty). Evidence for benefits on overall symptom burden, lung function, and exercise capacity is low to very low, and the effect on symptom duration remains unknown due to the lack of reporting.
