Pulmonary rehabilitation and sleep quality: a before and after controlled study of patients with chronic obstructive pulmonary disease.
Trial report in NPJ primary care respiratory medicine, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map.

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.

Abstract
backgroundPoor sleep quality is common in chronic obstructive pulmonary disease (COPD). It is associated with poor quality of life. Pulmonary rehabilitation (PR) improves quality of life, exercise capacity, and anxiety and depression. Its effect on sleep quality is uncertain.
aimTo determine whether PR improves sleep quality in COPD.
methodsA prospective controlled 'before and after' study of sleep quality in COPD patients attending a community PR programme was conducted. Sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI). Lung function, disease-specific quality of life (COPD assessment test--CAT), exercise capacity (incremental shuttle walk test--ISWT), and anxiety and depression (Hospital Anxiety and Depression Scale--HADS) were measured. Change in sleep quality was compared with a COPD control group.
resultsTwenty-eight participants completed PR. The control group comprised 24 patients. Prevalence of poor sleep quality (PSQI ≥5) was 78%. There were no differences between observation and control groups in sleep quality, age or severity. Quality of life was strongly correlated with quality of sleep (r=0.64, P<0.001). PR improved the quality of life (CAT change 3.0; 95% CI, 0.7-5.3), exercise capacity (ISWT change (metres) 81.0; 15.3-146.6), anxiety (HADS score ≥8: change 2.33; 0.45-4.22), and depression (HADS score ≥8: change 2.90; 1.92-3.88). PR did not improve sleep quality (PSQI mean change 0.79; -0.35 to 1.93).
conclusionsPR did not improve sleep quality in COPD despite improving quality of life, exercise capacity, anxiety and depression. New strategies, independent of PR, are required to improve sleep quality in COPD.
