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
Purpose: This study aimed to investigate the current practices of VTE prophylaxis in patients undergoing abdominal-pelvic surgery (PAS) and to identify the factors that influence surgeons' practice of VTE prophylaxis. Patients and Methods: This two-phase explanatory sequential mixed-method study used chart audits followed by semi-structured interviews based on the theoretical domain framework (TDF). During Phase I, quantitative data from 240 medical records of patients with PAS in April 2023 were audited to measure adherence rates to the standard thromboprophylaxis guidelines. In Phase II, in-depth interviews with 16 surgeons were conducted and analyzed using thematic content analysis based on the TDF framework to understand the determinants of thromboprophylaxis in patients with PAS. Results: Audits of 240 medical records of patients showed the rate of appropriate prophylactic methods was low (11.7%). For patients on anticoagulant prophylaxis, adherence rates regarding drug selection and dosage were high (100% and 89.3%, respectively), whereas adherence rates regarding time of initiation and length of prophylaxis were low (50% and 28.6%, respectively). A qualitative analysis identified 12 theoretical domains relevant to thromboprophylaxis practices among surgeons. The most encountered barriers included concerns about bleeding risk, resource issues, low beliefs about preventive benefits for certain patients with PAS, inadequate knowledge and training, and a lack of protocol and policy. The most encountered enablers included positive beliefs in prophylaxis benefits, mandatory policy and computerized supportive tools, thromboprophylaxis set as patient safety goals, leadership and multidisciplinary working, and training. Conclusion: Significant quality gaps were present in VTE prevention practice for abdominal-pelvic surgical patients, and multiple coexisting factors prevented the full adoption of practice standards. The implementation of an anticoagulation stewardship program is essential for addressing practical issues.
