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
objectiveAssociation between intrinsic capacity (IC) and venous thromboembolism (VTE) remains unclear, we aim to explore the relationship among IC, genetic predisposition, and incident VTE.
methodsIn this large retrospective cohort study using the UK Biobank, IC, defined as the composite of all physical and mental capacities of an individual, was assessed across 7 factors (such as exhaustion, sleep duration, eye problems, hearing difficulty, weight loss, gait speed, and grip strength) and scored from 0 (best) to 7 (worst). Participants were grouped into five IC categories: 0, 1, 2, 3, and ≥4 factors. Incident VTE was identified through national medical records. Genetic predisposition to VTE was determined by the tertiles of polygenic risk score (PRS) derived from external genome-wide association data from the UK Biobank. Cox proportional hazards models were used to investigate the associations with multiple variables adjusted.
resultsA total of 415,581 participants (median age, 57.0 years; interquartile range, 50.0-63.0; 54.96% female; 94.89% White) were included in the final analysis. Over a median follow-up of 14.37 years, 8299 (2.00%) developed VTE, including 3878 (0.94%) with and 4421 (1.07%) without a history of cancer. Higher IC scores were associated with increased VTE risk compared to those with IC = 0 (for IC = 1: hazard ratio (HR), 1.08; 95% confidence interval (CI), 1.01-1.16; P = .029; for IC = 2: HR, 1.12; 95% CI, 1.04-1.22; P = .005; for IC = 3: HR, 1.19; 95% CI, 1.06-1.34; P = .003; for IC ≥ 4: HR, 1.46; 95% CI, 1.23-1.75; P < .001). Similar associations were observed in both cancer and noncancer subgroups. Furthermore, individuals with both the highest PRS and the worst IC (≥4 factors) had the greatest VTE risk, with significant interactions between PRS and IC.
conclusionsOur large-scale study suggests that poor IC is an independent risk factor for VTE. Moreover, integrating IC with genetic risk can identify a high-risk subgroup, which supports the clinical utility of IC assessment in VTE risk stratification.
