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
Objective: To investigate the incidence and risk factors of preoperative deep vein thrombosis (DVT) in patients with periprosthetic hip fractures. Methods: This retrospective clinical cohort study enrolled 95 patients with periprosthetic hip fractures who met predefined inclusion and exclusion criteria between January 2016 and December 2025. The cohort included 28 males and 67 females, with a mean age of 72.9 years (range, 39-96 years). According to Vancouver classification, there were 1 case of type A, 32 cases of type B1, 59 cases of type B2, 1 case of type B3, and 2 cases of type C. The interval from injury to hospital admission ranged from 1 to 150 days (mean, 10.9 days). All patients received bilateral lower-extremity venous ultrasonography for preoperative DVT screening. Patients were divided into DVT-positive and DVT-negative groups according to ultrasound findings. Univariate analyses were conducted to compare demographic data (age, gender), underlying comorbidities (hypertension, diabetes mellitus, coronary atherosclerotic heart disease, cerebral infarction, Results: The overall preoperative prevalence of DVT was 28.42% (27/95) among patients with periprosthetic hip fractures. Subgroup analysis stratified by thrombus location showed 1 case (1.05%) of proximal DVT, 2 cases (2.11%) of distal axial DVT, and 24 cases (25.26%) of calf muscular vein thrombosis. Univariate analysis revealed significant intergroup differences in the prevalence of history of coronary atherosclerotic heart disease and preoperative D-dimer levels between DVT-positive and DVT-negative groups ( Conclusion: The incidence of preoperative DVT is considerably high in patients with periprosthetic hip fractures. History of coronary atherosclerotic heart disease and elevated preoperative D-dimer (≥5.26 mg/L) are independent risk factors for preoperative DVT in patients with periprosthetic hip fractures, which should be paid great attention to clinically.
