Aerobic capacity and muscular strength in 179 Norwegian men and women aged 20-59 years with a substance use disorder: A cross-sectional study.
Article in PloS one, 2026. 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
Research has shown a robust inverse association between maximal aerobic capacity and muscular strength, and lifestyle related diseases and mortality. People with a substance use disorder have a higher prevalence of lifestyle-related diseases and a shorter life expectancy than the general population. There is a paucity in the literature of normative aerobic capacity and muscular strength variables in people with a substance use disorder. The main purpose of this study was to contribute to establish reference values on these key variables for this patient group, and to compare these data to normative values consisting of healthy age matched controls. A total of 179 men and women with diagnosed substance use disorder according to International Classification of Diseases-10 performed a maximal cardiopulmonary exercise test on a treadmill recording maximal oxygen uptake and maximal oxygen pulse, along with a muscular strength test in a hack squat machine assessing maximal leg strength. Patients with substance use disorder generally demonstrated lower- maximal oxygen uptake (⁓ 15%), maximal oxygen pulse (⁓ 10%) and muscular strength (⁓ 30%) across all age groups compared to comprehensive Norwegian and American reference materials of healthy age-matched populations. This could contribute to explain the higher prevalence of lifestyle related diseases and reduced longevity in this patient group.
