1 · What the graph read from 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.

2 · The registry

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

Exercise training is an integral component of the pulmonary rehabilitation program for patients with chronic obstructive pulmonary disease (COPD). The aim of this study was to systematically search the published literature and analyze the evidence on the efficacy of supplemental oxygen in improving outcomes during exercise training in patients with COPD. The PubMed, Scopus, Cochrane Central Register of Controlled Trials (CENTRAL) and Google scholar databases were searched electronically for articles in the English language published up to May, 2019. In total, 7 trials were included in this systematic review and meta-analysis. There was considerable heterogeneity amongst the included studies. Meta-analysis indicated no significant difference in power (random: MD = -2.38; 95% CI, -5.79 to 1.03; P=0.86) and maximum energy expenditure (VO
