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
purposeThe role of perioperative anticoagulation in the setting of peripheral arterial injury remains unclear. We hypothesized that early initiation of anticoagulation is associated with a reduced amputation rate without increasing bleeding complications.
methodsUsing the 2016-2019 ACS-TQIP database, adult patients with upper and lower extremity vascular injuries who underwent open arterial repair and received anticoagulation were included. Patients were divided into two groups: (1) early venous thromboembolism prophylaxis (≤ 24 h) and (2) late prophylaxis (> 24 h) following arterial repair. The primary outcomes were the rates of limb amputation and bleeding complications. Multivariable logistic regression was used to estimate the impact of timing and type of anticoagulation on the rates of limb amputation and bleeding complications.
results4379 patients were included, and 83.9% were males. 68.1% of patients received early anticoagulation, whereas 31.9% received late thromboprophylaxis. Low-molecular-weight heparin (LMWH) was used in 62.0% of patients, and unfractionated heparin (UFH) was administered in 34.3% of patients. Multivariable analysis showed that late initiation of thromboprophylaxis (OR = 1.69 [1.16-2.45], p = 0.006) and use of UFH (OR = 2.61 [1.80-3.79], p < 0.001) were associated with increased rate of amputation. Early initiation of anticoagulation (OR = 2.16 [1.63-2.85], p < 0.001) was associated with increased risk of bleeding complications requiring blood transfusions. Similarly, the use of UFH was associated with a higher rate of bleeding events compared to LWMH (OR = 2.61, [1.80-3.79], p < 0.001).
conclusionPatients with the operative repair of arterial injuries receiving early perioperative anticoagulation demonstrated an improved limb salvage outcome than those who received late thromboprophylaxis. Our data also suggest that early initiation of prophylaxis may be associated with increased bleeding risk, which may be attenuated using LMWH compared to UFH.
