Association between physical function and type 2 diabetes risk in older adults: a longitudinal analysis from the KoGES-Anseong cohort.
Article in European geriatric 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
purposeType 2 diabetes (T2D) is associated with functional decline in older adults, but whether baseline physical function predicts its incidence remains unclear. This study examined whether the Short Physical Performance Battery (SPPB) predicts incident T2D in older Koreans, and whether resting heart rate (RHR) modifies this association.
methodsWe included 1,041 community-dwelling adults aged ≥ 65 years (mean age = 72.2 years; 58.3% women) without T2D at baseline from the KoGES-Anseong cohort (2013-2020). SPPB scores were categorized as high (≥ 10) or low (< 10), and RHR was dichotomized at the median. Incident T2D was ascertained through fasting glucose, physician diagnosis, or diabetes medication. Cox proportional hazards models (adjusted for demographic, metabolic, and lifestyle factors) estimated hazard ratios (HRs) and 95% confidence intervals (CIs) over 5294 person-years of follow-up.
resultsHigh SPPB scores were associated with a lower risk of T2D (HR = 0.49, 95% CI 0.25-0.94). This association was observed only in participants with elevated RHR (HR = 0.37, 95% CI 0.17-0.81), but not in those with lower RHR. Among individual SPPB domains, only lower-extremity strength showed a significant association with reduced T2D risk.
conclusionIn older adults, superior physical function substantially reduces the risk of T2D, with lower-extremity strength as the primary contributor. Importantly, this benefit remains robust among individuals with elevated RHR, underscoring functional performance as a practical target for preventive strategies.
