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

backgroundPulmonary rehabilitation (PR) is a key intervention for chronic obstructive pulmonary disease (COPD); however, adherence remains suboptimal, particularly in patients with low physical activity (PA) despite preserved physical capacity (PC). This study aimed to identify factors associated with low PA, with a focus on patient-reported outcomes (PROs).

methodsIn this prospective study, COPD patients were categorized according to daily moderate-to-vigorous PA measured using Fitbit devices: ≥30 minutes/day ('Do do') and <30 minutes/day ('Don't do'). Baseline characteristics, pulmonary function, and exercise capacity assessed by 6-minute walk distance (6MWD) were evaluated. PROs included the modified Medical Research Council (mMRC) dyspnea scale, COPD Assessment Test (CAT), and Patient Health Questionnaire-9 (PHQ-9). Logistic regression analysis was performed to identify factors independently associated with low PA.

resultsAmong 96 patients, 44 were classified as 'Do do' and 52 as 'Don't do.' The 'Don't do' group showed significantly lower 6MWD (424 m vs. 488 m, p=0.005) and lower forced expiratory volume in 1 second (46.73% vs. 54.48%, p=0.005). They also reported higher dyspnea scores (mMRC 1.77 vs. 1.30, p=0.019). Greater breathlessness measured by CAT was independently associated with low PA (odds ratio, 1.31; 95% confidence interval, 1.06 to 1.62), even after adjustment for 6MWD and pulmonary function. This association persisted in patients with preserved PC.

conclusionLow PA in COPD is influenced not only by objective physical limitations but also by subjective symptom burden, particularly dyspnea. Integrating PROs into PR assessment may facilitate identification of barriers and improve adherence to rehabilitation programs.
