A meta-analysis of the effects of long-term oxygen therapy combined with exercise rehabilitation on exercise capacity, cardiopulmonary function, and quality of life in patients with COPD.
Synthesis in Frontiers in medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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 assess the effectiveness of long-term oxygen therapy (LTOT) combined with exercise rehabilitation vs. exercise rehabilitation alone in improving exercise capacity, cardiopulmonary function, and quality of life in chronic obstructive pulmonary disease (COPD) patients. Methods: A comprehensive literature search was conducted in the Chinese Biomedical Literature Database (CBM), Wanfang, China National Knowledge Infrastructure (CNKI), Cochrane Library, EMBASE, ScienceDirect, and PubMed for studies published from January 2010 to the present. Controlled clinical trials comparing oxygen therapy and/or exercise rehabilitation in COPD patients were included. Two independent reviewers extracted data and assessed risk of bias using the Cochrane Handbook (version 5.3). Meta-analysis was performed using RevMan 5.3. Results: Nine studies ( Conclusion: LTOT combined with exercise rehabilitation is more effective than exercise alone in improving exercise capacity, pulmonary function, and quality of life in COPD patients. However, cardiac benefits remain unclear, warranting further studies.
