Frailty and risk of venous thromboembolism in older adults: the Atherosclerosis Risk in Communities Study.
Article in Journal of thrombosis and haemostasis : JTH, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundFrailty may be a marker of risk for developing venous thromboembolism (VTE).
objectivesTo examine the relationship of frailty and its components with risk of incident VTE among older adults.
methodsWe examined 5551 participants of the Atherosclerosis Risk in Communities Study without a history of VTE, using visit 5 (2011-2013) as baseline (mean age, 75.4 years; 57.8% female; 21.5% Black race). Frailty status (frail, prefrail, or robust) was defined as having ≥3 components, 1 to 2 components, or no components, respectively, from assessments of weight loss, low grip strength, exhaustion, slow walking speed, and low physical activity. VTE events were identified from hospitalization records and adjudicated by physicians.
resultsIn total, 182 incident VTE events accrued over a median follow-up of 7.2 years. Participants who were frail, vs robust, had a hazard ratio (HR) for incident VTE of 2.20 (95% CI, 1.30-3.71) after accounting for demographics. Further adjustment for potential confounders only slightly attenuated the association (HR, 2.09; 95% CI, 1.23-3.55). When analyzed separately, frailty was associated with a fully adjusted HR of 2.46 (95% CI, 1.26-4.80) for provoked VTE and 1.56 (95% CI, 0.66-3.69) for unprovoked VTE. Of the frailty components, exhaustion, slow walking speed, and low physical activity were significantly associated with increased risk of incident VTE.
conclusionAmong this sample of older adults, frail participants had a 2-fold greater risk of incident VTE than robust participants. Exhaustion, slow walking speed, and low physical activity were frailty components identified as being predictors of incident VTE. Frailty status may be a means for identifying older adults at elevated VTE risk.
