Persistent health inequalities over 20 years among adults with intellectual disabilities who display behaviours that challenge: evidence from English primary care records.

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
backgroundAdults with intellectual disabilities who display behaviours that challenge (BtC) are more prone to poor health.
aimsThis study seeks to evidence the long-term health outcomes for those who display BtC.
methodWe conducted a longitudinal cohort study of adults with intellectual disabilities aged ≥18 years in England, using data from the Clinical Practice Research Datalink Aurum (January 2003 to December 2023) linked to Hospital Episode Statistics and Office for National Statistics. Main outcome measures were annual health checks, general practitioner referrals, emergency visits, out-patient attendance, in-patient admissions and mortality.
resultsAmong 83 166 adults with intellectual disabilities (mean age 38.6 years), 18.5% had a record of BtC, with similar sociodemographic distributions to those without BtC, but higher rates of physical and mental health comorbidities and uptake of annual health checks. A total of 72.5% of participants with BtC were receiving psychotropic medication(s). Adults with BtC had higher rates of mental health out-patient attendance (odds ratio: 1.42, 95% CI 1.33-1.52) and in-patient admissions (incidence rate ratio (IRR): 1.19, 95% CI 1.09-1.29), but consistently lower rates of physical health out-patient attendance (IRR = 0.81, 95% CI 0.78-0.84) and in-patient admissions (IRR = 0.77, 95% CI 0.74-0.79), after adjusting for demographic and clinical characteristics. BtC were not associated with mortality after adjustment for comorbidities (hazard ratio: 0.97, 95% CI 0.93-1.00).
conclusionsThis longitudinal study not only corroborated the markedly elevated burden of physical and mental health comorbidities among individuals displaying BtC, but also indicated that repeated efforts to improve health outcomes have yielded minimal measurable benefit over time. The apparent absence of progress is likely underpinned by a combination of insufficiently effective or poorly tailored interventions and wider systemic constraints that limit the capacity of services to respond to the complex needs of this population.
