Five-Year Trajectories of Disability in Older Adults Seeking Care for Back Pain in the Netherlands: BACE-Dutch Cohort.
Article in European journal of pain (London, England), 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
backgroundInvestigating trajectories in older people with back pain (BP) is informative for estimating prognosis and initiating personalized treatment. We aimed to identify 5-year trajectories of BP-related disability in older adults, and baseline factors associated with trajectory membership.
methodsWe used data from the BACE-Dutch cohort, which included older adults (≥ 55 years) seeking primary care for BP. Disability was measured with the Roland Morris Disability Questionnaire (RMDQ) at baseline, 6 weeks, 3, 6, 9 months and annually to 5 years. Latent class growth analysis (LCGA) identified trajectories; multinomial regression examined baseline predictors.
resultsWe included 669 participants. A four-class LCGA model provided the best fit and identified four trajectories: "Recovery trajectory" (38.5%; mean baseline RMDQ = 5.4; improved), "Incomplete recovery trajectory" (28.1%; mean baseline RMDQ = 9.6; improved), "Persistent moderate disability" (22.3%; mean baseline RMDQ = 13.3; stable), and "Persistent high disability" (11.1%; mean baseline RMDQ = 17.7; stable). Most disability improvement occurred within the first 6 months, and 66.6% of participants followed improved trajectories. Older age, higher BMI, higher pain intensity, presence of depressive symptoms, less optimistic back pain beliefs, BP history, and radiating leg pain were associated with membership to worse trajectories.
conclusionsWe identified four distinct 5-year trajectories of disability in older people with BP. Most patients followed a trajectory with very low disability, while the smallest group followed a high disability trajectory. Baseline age, BMI, pain intensity, BP history, radiating leg pain, depression, and negative expectations were associated with trajectory membership. SIGNIFICANCE STATEMENT: In Dutch primary care, older adults with back pain show four distinct disability trajectories. Baseline characteristics associated with subgroup membership help identify patients at risk of poorer outcomes, providing input for risk stratification and a personalized care approach.
