The impact of cancer diagnosis on functional decline in adults aged 50 and older: the US Health and Retirement Study.
Article in Journal of cancer survivorship : research and practice, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 1 paper.
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
purposeWe conducted a longitudinal secondary data analysis to estimate long-term functional limitation trajectories of adults over 50 with cancer compared to cancer-free individuals.
methodsUsing the Health and Retirement Study (1998-2020), we followed adults over 50 without cancer history. Incident cancer was self-reported or proxy reported. Functional decline was assessed using self-reported independence in six domains, including instrumental activities of daily living (IADL), activities of daily living (ADL), mobility, large muscle, gross motor, and fine motor skills. We employed linear probability models with repeated measures to estimate independence probabilities.
resultsAmong 15,972 participants (mean [SD] age, 66.1 [9.9] years), 23.1% reported cancer during follow-up. Before diagnosis, individuals with cancer had a 1.3% lower probability of IADL independence compared to cancer-free individuals (95% CI = - 1.9, - 0.7). After diagnosis, cancer survivors experienced a sharp 6% drop in IADL independence, resulting in a 3.4% lower probability than in those without cancer (- 4.6, - 2.2). The annual rate of IADL decline after diagnosis was slower in cancer survivors compared to those without cancer (- 0.9% vs. - 1.3%). Similar patterns were observed for ADL. The greatest immediate reduction was in the gross motor domain with a decline of 8.6% (- 10.4, - 6.8).
conclusionsCancer survivors experienced rapid functional decline at diagnosis, possibly attributed to active treatment. Following diagnosis, cancer survivors had a more gradual loss in functional independence compared to cancer-free individuals. IMPLICATIONS FOR CANCER SURVIVORS: Findings underscore the importance of proactive, tailored interventions to support functional independence in older cancer survivors, particularly around diagnosis.
