Risk Factors of Delirium Following Reconstructive Surgery for Head and Neck Tumors: A Retrospective Clinical Trial.
Article in Therapeutics and clinical risk management, 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
Background: Patients after head and neck tumor reconstruction surgery frequently require deep sedation and analgesia in the ICU. However, the risk factors for delirium associated with propofol-based sedation remain unclear. Objective: The study aimed to explore the risk factors of delirium of propofol singled or combined sedation. Methods: This retrospective study analyzed ICU patients who underwent head and neck tumor reconstruction surgery. The patients were divided into three groups: propofol (P), propofol + midazolam (PM), and propofol + dexmedetomidine (PD) groups. We utilized univariate and multivariate logistic regression to identify risk factors of delirium. Results: Delirium occurred in 4 (7.02%), 11 (28.21%), and 5 (20.83%) patients in the P, PM and PD groups, respectively. Elevated mean arterial pressure (MAP), increased aspartate aminotransferase (AST) levels, and the combined use of midazolam were determined to be significant risk factors for delirium in this patient cohort. The combined use of midazolam is the strongest predictor of delirium, which can increase the risk of delirium by 3.218 times (95% CI = 1.041-9.950, p = 0.042). Conclusion: Propofol combined with midazolam for sedation in patients after head and neck tumor reconstruction surgery may increase the risk of delirium.
