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
Aims & objectives: The risk of postoperative venous thromboembolism (VTE) and bleeding after operative management of femoral neck fractures (FNF) is well established. It is common for FNF patients to be discharged to rehabilitation facilities, despite higher complication rates. It was hypothesized that discharge to rehabilitation after operative fixation of FNF was associated with increased risk of VTE and bleeding. Materials & methods: Retrospective review of 7483 patients who sustained FNF and underwent operative treatment between 1/1/2019-12/31/2021 was conducted using a commercial claims database. The primary outcome was VTE and bleeding post-discharge within 30 days of surgery. Risk factors for VTE and bleeding were evaluated by logistic regression analysis. Results: The cumulative incidence was 3.77 % (95 % confidence interval (CI) = 3.33-4.21) for VTE and 4.01 % (CI = 3.56-4.46) for bleeding. There were 56.7 % of patients who were discharged to rehabilitation. Multivariable analysis demonstrated hereditary hypercoagulable diagnosis (odds ratio (OR) = 2.86, CI = 1.33-6.16), discharge to rehabilitation (OR = 2.08, CI = 1.47-2.92), discharge to another location (OR = 1.94, CI = 1.15-3.27), and length of stay (LOS) ≥5 days (OR = 1.69, CI = 1.15-2.50) increased risk for postoperative VTE. Variables that increased risk of bleeding included discharge to rehabilitation (OR = 2.20, CI = 1.55-3.12), discharge to other (OR = 1.92, CI = 1.12-3.27), and chronic anticoagulation (OR = 1.58, CI = 1.19-2.10). Analysis of patients prescribed thromboprophylactic medications demonstrated cumulative incidence of VTE 3.46 % (CI = 2.24-4.68) and 4.47 % (CI = 3.09-5.85) for bleeding at 30 days. Conclusion: In patients with FNF, discharge to inpatient rehabilitation was associated with increased risk of postoperative VTE and bleeding. LOS ≥5 days was also associated with increased VTE risk, demonstrating the importance of timely hospital discharge.
