Predictors of Venous Thromboembolism Following Geriatric Distal Femur Fracture Fixation: Are These Patients at Higher Risk Compared With Hip Fracture Patients?

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) following injury and subsequent fixation of a distal femur fracture (DFFx) is associated with considerable morbidity. However, the incidence of VTE, associated factors, and the relative risk compared with hip fracture (HFx) fixation remains poorly characterized.
methodsRetrospective cohort study using the PearlDiver M165 database to identify geriatric patients who underwent DFFx and HFx fixation. Clinical risk factors of VTE within 90 days of DFFx and the risk modification associated with enoxaparin (Lovenox) and direct oral anticoagulants (DOACs) relative to aspirin/nonprescription agents were characterized. To determine the odds of VTE following fixation of DFFx relative to HFx, a matched comparison based on age, sex, and Elixhauser Comorbidity Index was done.
resultsOf 24,358 DFFx patients, 1684 (6.9%) developed VTE. Independent risk factors included a prior VTE (odds ratio [OR] 28.76), displaced DFFx morphologies (condylar [OR 5.44], and supracondylar without intracondylar extension [OR 3.96] and with extension [OR 3.75]), active cancer (OR 2.11), coagulopathy disorder (OR 1.15), and younger age (OR 1.03) (P < 0.05 for all). Lovenox and DOAC were both associated with reduced odds of VTE (OR 0.40 and OR 0.61, respectively) (P < 0.05 for both). Relative to HFx patients, DFFx patients demonstrated heightened odds of VTE (OR 1.25) (P < 0.001). DISCUSSION: This study identified a relatively high rate of VTE, 6.9% within 90 days, following surgical management of DFFx and heightened odds of VTE relative to HFx patients. Various factors demonstrated a notable association with increased odds of VTE, although both Lovenox and DOACs may be effective therapeutic options for risk mitigation.
