Article in BMC pulmonary medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06330623 (Developing Personalised, Relative Intensity Physical Activity Thresholds for Accelerometer-Derived Measures of Physical Activity in COPD), which is not on this map.

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.

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

backgroundPhysical activity (PA)-related health benefits are greatest for activity undertaken at higher intensities. However, individuals living with Chronic Obstructive Pulmonary Disease (COPD) often find engaging in higher-intensity PA challenging. Due to the lack of qualitative research on how those with COPD perceive PA intensity, this photovoice study explores how PA intensity is experienced in day-to-day living.

methodsSemi-structured interviews, enhanced by photovoice, were conducted with individuals with COPD and other comorbidities to explore their perceptions of PA intensity in daily life. Participants captured images over 7 days to illustrate how their conditions impact their PA. The participant-generated images were used in the interviews. Reflexive inductive thematic analysis was used to generate themes.

resultsThirteen interviews were conducted (54% female, aged 64 ± 6 years), generating two main themes. Theme 1 focused on how individuals employ strategies to manage the intensity of their PA: breaking down PA, pacing themselves or trying to do the activity all in one go. Theme 2 highlighted the reciprocal relationship between participants and their family/friends regarding PA intensity. Family/friends often ensure individuals do not "overdo it" while participants may influence the intensity of their family/friends activities, sometimes requiring family/friends to slow down or stop.

conclusionThis study provides insights into the social complexities and strategies used to manage PA intensity in daily life, which can inform behavioural interventions to increase participation in higher-intensity PA among people with COPD.

trial registrationThe study was retrospectively registered on Clinical Trials.gov (Identifier: NCT06330623) on the 26th of March 2024.
