Development of a prediction model for lower limb deep vein thrombosis in critically ill patients after intracranial hemorrhage at high altitude: a retrospective study.
Article in PeerJ, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 analyze the risk factors for lower limb deep vein thrombosis (LDVT) in critically ill patients admitted to the intensive care unit (ICU) following intracranial hemorrhage at high altitude, and to establish a predictive model. Methods: A retrospective analysis was conducted on 359 patients who underwent surgery for intracranial hemorrhage and were admitted to the ICU of Xizang Autonomous Region People's Hospital between August 1, 2021, and December 31, 2023. Patients were categorized into an LDVT group ( Results: Compared to the non-LDVT group, patients in the LDVT group had significantly longer ICU and overall hospital stays ( Conclusion: LDVT significantly prolongs ICU and hospital stays in critically ill patients. Hypoalbuminemia and elevated D-dimer levels are independent risk factors for LDVT, whereas aboriginal residency at high altitudes (≥ 4,500 m) serves as a protective factor. The developed risk prediction model shows strong predictive performance.
