Effect of a pulmonary rehabilitation programme of 8 weeks compared to 12 weeks duration on exercise capacity in people with chronic obstructive pulmonary disease (PuRe Duration): protocol for a randomised controlled trial.
Article in BMJ open respiratory research, 2020. 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
introductionPulmonary rehabilitation (PR) is a key component in the management of chronic obstructive pulmonary disease (COPD). There is no strong evidence on the optimal duration of PR programmes. The aim of this study is to determine whether an 8-week PR programme is equivalent to a 12-week PR programme in people with COPD. METHODS AND ANALYSIS: This study will be a prospective, multisite, randomised controlled, equivalence trial with assessors blinded to group allocation and intention-to-treat analysis. 72 participants with COPD will be recruited and randomised to either a supervised, twice weekly for 8 weeks or a 12-week PR programme of exercise training and education. PRIMARY OUTCOME: endurance shuttle walk test. SECONDARY OUTCOMES: will include St George's Respiratory Questionnaire, 6-min walk distance, COPD assessment test, Hospital Anxiety and Depression Scale, physical activity monitoring and hospital admissions at 6 months and 12 months. Repeated measures analysis of variance will be used to analyse differences between the groups for all outcomes. ETHICS AND DISSEMINATION: Ethics approval was gained from all participating sites. Results of the trial will be submitted for publication in a peer-reviewed journal. TRIAL REGISTRATION NUMBER: ACTRN12616001586404.
