Changes in Frailty and Incident Cancer: Evidence From the Health and Retirement Study.
Article in Journal of cachexia, sarcopenia and muscle, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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.
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
backgroundAlthough frailty has been identified as a potential risk factor for cancer, most previous studies have only considered frailty status at a single time point. The relationship between dynamic changes in frailty and incident cancer is less well understood. This study aimed to evaluate the associations of both baseline frailty status and changes in frailty status with subsequent cancer risk.
methodsData were derived from the Health and Retirement Study (HRS), a nationally representative prospective cohort in the United States. Frailty was assessed using a 29-item Rockwood frailty index and categorized as robust, pre-frail or frail. Changes in frailty status were determined over a 2-year period. Incident cancer was identified through self-reported physician diagnoses. Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs), adjusting for demographic, lifestyle and health-related covariates.
resultsA total of 11 661 participants (63.1% female; mean age: 67.1 years) were included in the baseline frailty analysis, and 10 178 participants (63.8% female; mean age: 66.3 years) were included in the frailty change analysis. During a median follow-up of 7.2 years, baseline frailty was associated with a significantly increased risk of incident cancer (frail vs. robust: HR 1.61, 95% CI 1.27-2.02; pre-frail vs. robust: HR 1.46, 95% CI 1.17-1.83). Over the 2-year transition period, participants who progressed from robust to pre-frail/frail status had a higher cancer risk compared to those who remained robust (HR 2.50, 95% CI 1.74-3.61). Conversely, frail individuals who improved to pre-frail or robust status had a reduced cancer risk relative to those who remained frail (HR 0.66, 95% CI 0.48-0.90). Similar risk reduction was observed among pre-frail individuals who recovered to robust status (HR 0.51, 95% CI 0.34-0.76). Additionally, greater increases in frailty index over timeremained associated with elevated cancer risk after multivariable adjustment (highest vs. lowest quartile of ΔFI: HR 1.35, 95% CI 1.13-1.63; p for trend < 0.001).
conclusionsBoth baseline frailty and changes in frailty status are independently associated with cancer risk. Frailty progression significantly increases the risk of incident cancer, whereas recovery from frailty is associated with reduced risk. These findings underscore the importance of dynamic frailty monitoring and suggest that interventions targeting frailty warrant investigation for potential cancer risk reduction.
