Outdoor Exercise for People with Rheumatic Disease-Study Protocol and Baseline Characteristics of the OUTdoor Physical ACtivity Cohort (OUTPAC).
Article in International journal of environmental research and public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
The OUTPAC cohort study evaluates the setup and implementation of a nationwide Danish initiative focused on the impact of structured outdoor physical activity (PA) on individuals with rheumatic diseases. This prospective cohort study includes more than 1600 participants, predominantly women (92%), with an average age of 65 years (range: 28-93). The cohort primarily consists of individuals with osteoarthritis (72%), rheumatoid arthritis (18%) and nonspecific lower back pain (13%). Volunteer instructors conducted interventions in outdoor settings, targeting strength, balance, physical capacity, mental health, and interaction with nature. Data collection involved questionnaires and physical tests in four primary outcome domains: quality of life, pain, physical function and activity, and mental health. Despite moderate pain (VAS mean: 48.3), high medication use (71%), and serious fatigue (54%), participants indicated having a good quality of life (EQ-5D-5L mean: 0.81) and average mental health (WHO-5 mean: 62.9). Baseline scores from physical tests showed results comparable to the general population aged 60-69 years. The OUTPAC project offers clinical insight into the implications of outdoor PA interventions on individuals with rheumatic disease while shedding light on the development and implementation of a large-scale nationwide outdoor PA intervention. Future analyses will examine short- and long-term changes and potential determinants.
