Supplemental oxygen for symptomatic relief in people with serious respiratory illness: a systematic review and meta-analysis.
Synthesis in European respiratory review : an official journal of the European Respiratory Society, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundPeople with serious respiratory illness frequently have a high symptom burden and may be prescribed supplemental oxygen therapy with the aims of reducing the severity of breathlessness and improving health-related quality of life (HRQoL). This systematic review and meta-analysis aimed to assess the effectiveness of oxygen therapy
methodsA comprehensive search was performed in Embase, Medline and the Cochrane Central Register of Controlled Trials for randomised controlled trials published prior to June 2022. We used the Cochrane Risk of Bias Tool for appraising the studies and conducted random-effect meta-analyses when appropriate. We pooled effects recorded on different scales as standardised mean differences (SMDs) with 95% confidence intervals. Lower SMDs indicated decreased breathlessness or HRQoL. We assessed the certainty of evidence using the Grading of Recommendations, Assessment, Development and Evaluation framework.
resultsWe found that supplemental oxygen (compared with sham air or no treatment), reduced breathlessness intensity during laboratory exercise testing (SMD -0.75, 95% CI -1.23--0.28, 12 randomised control trials (RCTs), 245 participants), but had no shown effect on breathlessness measured in daily life (SMD -0.08, 95% CI -0.41-0.26, one RCT, 213 participants) or HRQoL (SMD -0.06, -0.17-0.05, 14 RCTs, 1062 participants). Few or no adverse events related to oxygen therapy were reported. For all the outcomes, the certainty of evidence was low.
conclusionsOxygen improved exertional breathlessness in laboratory-based exercise studies but was not shown to improve breathlessness or HRQoL in daily life.
