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

Background: The use of positive expiratory pressure (PEP), which includes conical-PEP breathing, has been proposed for use during exercise among patients with chronic obstructive pulmonary disease (COPD) to reduce dynamic hyperinflation (DH) and improve exercise capacity. However, evidence on the effects of exercise training with conical-PEP for pulmonary rehabilitation (PR) remains limited. This study was conducted to evaluate the aforementioned effects on exercise capacity, DH, and quality of life among patients with moderate to very severe COPD. Methods: Forty-two patients with moderate to very severe COPD were assigned to a home-based PR program. They were then randomly allocated to exercise training with conical-PEP ( Results: There were no significant differences in 6MWD ( Conclusion: The addition of conical-PEP during exercise training for PR in COPD did not provide significant benefits over exercise training without conical-PEP. Further research is warranted.
