Change in self-reported activity in chronic low back pain after 13 years - a prospective longitudinal cohort study in primary healthcare.
Observational study in BMC musculoskeletal disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03974191 (13-year Follow-up of Women With Chronic Low Back Pain in Primary Care - a Prospective Longitudinal Cohort Study), which is not on this map. Cited by 2 papers.
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.

Abstract
backgroundThe knowledge about the improvement of body function, activity and participation in chronic low back pain (CLBP) over a period of over ten years is still insufficient. The study aimed to investigate the long-term change for body function, self-reported activity due to CLBP e.g. Roland Morris Disability Questionnaire (RMDQ) and work participation.
methodsA 13-year prospective longitudinal cohort study of women with CLBP seeking primary healthcare. Women (n = 130) with CLBP (> 12 weeks) were included in 2004 to 2005 (baseline), after two and 13 years. The assessment included questions about socio-demographic data, comorbidity, and pharmacological treatment, physical capacity-tests, and patient reported outcome questionnaires. Changes in measurements, for physical capacity, pain intensity, pain localisations, RMDQ, symtoms of anxiety and depression, clinical stress symptoms, and health-related quality of life, between baseline and the 13-year follow-up were calculated. Depending on the data level and distribution, either parametric or non-parametric tests were applied. A mixed effect model was used to analyse repeated measures of RMDQ from baseline to the two-year and 13-year follow-ups, comparing the group with localised CLBP and CLBP + widespread pain (WP) group. The RMDQ was dependent variable and age, education level, pain intensity, 6-Minute Walk Test, symptoms of stress, and depression were included as confounding factors.
results67% (87/130) could be followed up after 13 years. 26% of the participants (22/86) fulfilled the criteria for WP at baseline. All measurements showed small improvements or were stable, except for hand grip strength. The mean change in RMDQ was − 3.3 (4.1) points. 73% (63/86) improved at least one point and 40% (34/86) improved ≥ 5 points on RMDQ from baseline. RMDQ improved in both the groups CLBP and CLBP + WP over the 13-year period (p < 0.001) when adjusting for age, education, pain intensity, 6-Minute Walk Test, symptoms of stress, and depression.
conclusionsAll outcome measurements, except for hand grip force either showed small improvements or remained stable over a period of 13 years. For activity related to CLBP, no differences were found between the CLBP group and the CLBP + WP group when adjusting for pain intensity, physical capacity, stress, and depression. 40% improved with clinical important change in self-reported activity related to CLBP over a period of 13-years, which is important information to provide to individuals seeking primary healthcare for CLBP.
