Identifying classes with different disability profiles amongst patients with persistent neck pain.
Article in Journal of rehabilitation medicine, 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
objectiveTo identify latent classes with distinct disability profiles among patients with persistent neck pain using item-level responses from the Neck Disability Index, and to examine demographic, clinical, and lifestyle factors associated with class membership.
designCross-sectional survey-based study. PATIENTS: 962 patients with persistent neck pain.
methodsThis survey-based study included 962 patients with persistent neck pain. Latent class analysis was performed using the 10 dichotomized items of the Neck Disability Index (NDI) as indicator variables. Demographic, clinical, and lifestyle characteristics were subsequently examined across the identified latent classes.
resultsThe mean age was 50 (SD 32.5) years and 647 (67%) were women. Three distinct classes were identified: class with no or mild disability (47% of the sample); class with moderate disability in reading, driving, and lifting but not in personal care and concentration (15% of the sample); and class with overall severe disability (37% of the sample). Lower educational level, obesity, physical inactivity, worse pain, and lower occupational status were associated with a higher probability of belonging to the severe disability class.
conclusionPatients with persistent neck pain appear to exhibit distinct disability profiles rather than a single uniform pattern of functional limitation. Identifying these profiles may improve the characterization of patient heterogeneity and provide a basis for future research evaluating their clinical and prognostic relevance. Further studies are needed to determine whether these profiles are reproducible in other populations and whether they have implications for treatment planning and outcomes.
