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: This study aimed to develop a structured risk assessment system for postoperative lower extremity deep vein thrombosis (LEDVT) in patients with severe traumatic brain injury (sTBI), and to validate its content and reliability through expert consensus. Methods: The system was designed based on evidence from a comprehensive literature review and refined through a two-round Delphi expert consensus process involving 16 multidisciplinary experts. Indicator weights were assigned using an analytic hierarchy process combined with expert scoring. Results: The finalized framework incorporated 6 primary domains-demographic characteristics, trauma-related indicators, coagulation parameters, comorbidities, iatrogenic factors, and venous thromboembolism prophylaxis-encompassing 19 secondary indicators. Response rates for two rounds of the expert questionnaire were 100%. The expert authority coefficient was 0.931. The coefficients of variation for the second-round indicators ranged from 0% to 7.01% and Kendall's coefficient of concordance was 0.670 ( Conclusion: A comprehensive risk prediction indicator system for LEDVT following sTBI surgery was established. The system is suitable for direct integration into hospital information systems, with weighted indicators reflecting clinical priorities and supporting the development of real-time monitoring modules.By enabling early identification of high-risk patients, this tool can facilitate timely prophylactic interventions, enhance clinical decision-making, and ultimately reduce the incidence of postoperative LEDVT, thereby improving patient safety and overall quality of care.
