Comparing physical activity practice, pain and psychological characteristics in individuals with fibromyalgia and individuals with low back pain.
Article in Chiropractic & manual therapies, 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
backgroundChronic primary low back pain (CLBP) and fibromyalgia (FM) have complex etiologies and management approaches. Further research is needed, particularly on subgroups like individuals with CLBP who also report signs and symptoms of FM (CLBP/FM+) to better understand their pain mechanisms and clinical profile. Examining psychological, pain-related characteristics, and physical activity could help identify subgroups of individuals with CLBP/FM+ and guide the development of targeted interventions. This study aimed to compare physical activity practice, pain and psychological characteristics of individuals with CLBP without signs and symptoms of FM (CLBP/FM-), CLBP/FM + and FM to better understand similarities and differences between these chronic pain conditions.
methodsNinety-four individuals self-reporting CLBP (83% women) and 101 individuals self-reporting FM (96% women) were recruited online and completed a 30-min online survey. Among those with CLBP, 39 were classified as CLBP/FM+ and 55 as CLBP/FM-. Analyses of variance (ANOVAs) with polynomial contrasts were conducted to assess linear trends across the three groups on pain intensity (Numeric Rating Scale), psychological characteristics (Short Form-12, Tampa Scale for Kinesiophobia) and physical activity practice.
resultsIndividuals with CLBP/FM- were more likely to participate in high-intensity physical activities. The analysis revealed a significant linear trend across the CLBP/FM-, CLBP/FM+, and FM groups for all pain and psychological characteristics except for the physical component of the quality of life and moderate-intensity physical activity.
conclusionsIndividuals reporting a diagnosis of FM exhibit greater symptoms severity and engage less in high-intensity physical activities than individuals with CLBP/FM+ and CLBP/FM-. Identifying a subgroup of individuals with CLBP/FM+ may help recognize mixed pain profiles and inform more personalized tailor management strategies.
