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

The six minute walk test (6MWT) has a prognostic role in patients with chronic obstructive pulmonary disease (COPD). The aim of this study was to determine the factors associated with desaturation during the 6MWT in patients with COPD. This study utilized data from the prospective KOrea COPD Subgroup Study (KOCOSS) cohort. The results of the 6MWT performed at enrollment were analyzed in this study. A total of 1789 participants performed the 6MWT. Among them, 185 (10.3%) experienced desaturation during 6MWT. Old age, ex-smoker, low forced expiratory volume in one second (%), and high COPD assessment test score were significantly associated with exertional desaturation.
