Supplementary oxygen efficacy for chronic pulmonary disorders and exertion desaturation.
Article in ERJ open research, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Introduction: Exertion-induced desaturation (EID) is a common complication of numerous pulmonary disorders and often treated with supplementary oxygen during exertion. We performed a systematic review and meta-analysis of randomised clinical trials (RCTs) to evaluate the efficacy of supplementary oxygen for EID in pulmonary disorders. Material and methods: Medline and Embase were systematically searched from July 2022 to June 2023 following PRISMA guidelines. RCTs that met predefined inclusion criteria were included. Means and standard deviations were extracted and standardised mean differences (SMDs), the difference in means between groups divided by the standard deviation, and 95% confidence intervals were calculated. Exercise capacity was the primary outcome; exercise dyspnoea, baseline dyspnoea and quality of life were secondary objectives. The immediate, post-rehabilitation, short-term and ambulatory effects of oxygen supplementation were evaluated. Results: We included 15 studies in our analysis. Oxygen supplementation to treat adult EID had been investigated for COPD and idiopathic pulmonary fibrosis (IPF) only. Oxygen supplementation was superior to placebo for its immediate effect on exercise capacity for COPD (SMD 0.42, 95% CI 0.15-0.69, I Conclusions: Our study revealed the efficacy of supplemental oxygen for EID and only a positive immediate effect on exercise capacity and dyspnoea, but no improvement in other short-term or long-term measures.
