Weight-Based Dosing for Venous Thromboembolism Prophylaxis in Spinal Trauma Patients Appears Safe.
Article in The Journal of surgical research, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
introductionVenous thromboembolism (VTE) is a substantial cause of morbidity and mortality in trauma patients. VTE prophylaxis (VTEP) initiation is often delayed in certain patients due to the perceived risk of bleeding complications. Our VTEP guideline was changed from fixed-dosing to a weight-based dosing strategy using enoxaparin in June 2019. We investigated the rate of postoperative bleeding complications with a weight-based and a standard dosing protocol in traumatic spine injury patients requiring surgical stabilization.
methodsA retrospective pre-post cohort study using an institutional trauma database was conducted, comparing bleeding complications between fixed and weight-based VTEP protocols. Patients undergoing surgical stabilization of a spine injury were included. The preintervention cohort received fixed-dose thromboprophylaxis (30 mg twice daily or 40 mg daily); the postcohort received weight-based thromboprophylaxis (0.5 mg/kg q12 h with anti-factor Xa monitoring). All patients received VTEP 24-48 h after surgery. International Classification of Diseases codes were used to identify bleeding complications.
resultsThere were 68 patients in the pregroup and 68 in the postgroup with comparable demographics. Incidence of bleeding complications in the pre- and postgroups were 2.94% and 0% respectively.
conclusionsVTEP initiated 24-48 h after surgical stabilization of a spine fracture using a weight-based dosing strategy and has a similar rate of bleeding complications as a standard dose protocol. Our study is limited by the low overall incidence of bleeding complications and small sample size. These findings could be validated by a larger multicenter trial.
