Risk Factors for Emergence Delirium in Elderly Orthopedic Patients After General Anesthesia.
Observational study in Brain and behavior, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectiveThe primary objective of this research was to investigate the occurrence rate and independent risk factors associated with emergence delirium (ED) in elderly patients undergoing orthopedic procedures with general anesthesia, providing a basis for clinical prevention and intervention.
methodsElderly individuals (age ≥65 years) undergoing orthopedic procedures under general anesthesia with subsequent post-anesthesia care unit (PACU) admission were included in this secondary analysis of a prospective observational study. ED was assessed at 10 and 30 min after PACU admission and immediately before discharge using the Nursing Delirium Screening Scale. Univariate logistic regression was first employed to screen potential risk factors, after which multivariate logistic regression analysis was conducted to determine independent risk factors.
resultsED was observed in 85 individuals, accounting for 35.1% of the 242 patients. Multivariate logistic regression analysis showed that the presence of urinary catheters (odds ratio [OR] 4.30, 95% confidence interval [CI] 2.08-8.91), age (OR 1.14, 95% CI 1.08-1.20), postoperative numerical rating scale score (OR 1.37, 95% CI 1.08-1.73), and fasting times for solids (OR 1.10, 95% CI 1.02-1.19) were independent risk factors for ED. The multivariate model demonstrated acceptable discrimination with an area under the curve of 0.77 and excellent calibration (Hosmer-Lemeshow test, p = 0.637).
conclusionED represents a common complication following general anesthesia in elderly orthopedic patients. Some risk factors, including the presence of urinary catheters, prolonged fasting times for solids, advanced age, and postoperative pain, can increase the incidence of ED. Perhaps we can reduce the occurrence of ED through multimodal clinical strategies.
