Activity behaviours and quality of life in patients with malignant pleural effusion.
Article in ERJ open research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background and objective: Accelerometery is used to measure activity behaviours in patients with malignant pleural effusion (MPE). This study aimed to evaluate physical activity and sedentary behaviour profiles of patients with MPE in Hong Kong, and to explore relationships between activity behaviours and quality of life (QoL). We also compared clinician-recorded performance status measures with objective measures of activity levels. Methods: Participants wore an Actigraph GT3X+ accelerometer continuously for 7 consecutive days. The EuroQoL 5 Dimensions 5 Levels (EQ-5D-5L) was used to assess five dimensions of QoL and correlate with activity behaviours. The Eastern Cooperative Oncology Group (ECOG) performance status was documented by clinicians at baseline. Results: Fifty-one patients with MPE received accelerometers; 94% had ≥1 valid day of data. Participants spent 76% (sd 2.32) of waking hours sedentary, 23% (sd 1.40) of waking hours in light activity and 0.3% (median, interquartile range 0.0-1.5) in moderate-to-vigorous physical activity (MVPA). Higher light activity and MVPA behaviours were associated with increased participation in self-care tasks (r Conclusion: This is the first report of physical activity behaviours in patients with MPE in Hong Kong, demonstrating high sedentary behaviours and low physical activity which correlated to dimensions of QoL. Clinician-rated performance status was not reflected in accelerometery data, suggesting a discrepancy between performance status measures and objective measures of activity in patients with MPE.
