Association of age on thromboelastography coagulation profiles among elderly patients with peripheral arterial disease.

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
objectiveThis study aimed to determine whether age affects thromboelastography (TEG) coagulation profiles among elderly patients with peripheral arterial disease. We hypothesized that TEG parameters would not significantly differ between age groups when controlled for anticoagulation regimen.
methodsThis was a prospective, single-institution, observational study that included patients aged 65 years and older who underwent open or endovascular lower extremity revascularization for peripheral arterial disease from December 2020 through December 2023. A total of 158 patients were grouped into categories: by age (65 to 74 years and 75+ years) and anticoagulation regimen (single antiplatelet [50%], dual antiplatelet [15%], therapeutic anticoagulation [27%], none [8%]). Objective TEG coagulation profiles were collected preoperatively and were compared among patient groups. One-way analysis of variance was used to compare three or more groups of continuous data, and χ
resultsAmong 158 patients (36.4% female; median age, 74.5 ± 6.6 years), there were no significant differences in TEG parameters (reaction time, maximum amplitude, lysis at 30 minutes, angle, adenosine diphosphate % aggregation, adenosine diphosphate % inhibition) between age groups when stratified by anticoagulation regimen (all P > .05). Thrombosis rates were similar between age groups (21.1% vs 20.6%; P = .936), but mortality was significantly higher in the 75+ group (20.6% vs 5.6%; P = .005).
conclusionsObjective coagulation parameters do not appear to vary significantly among age groups within the elderly population when controlled for antiplatelet/anticoagulant regimen. TEG profiles may be used to guide anticoagulation management among elderly patients. Further studies can help elucidate the full utility of TEG profiles for coagulation surveillance among elderly patients.
