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 clinical epidemiological characteristics, treatment trends, and risk factors for in-hospital mortality in patients with aortic dissection (AD) at a single center, so as to provide references for early diagnosis and intervention in the emergency department. Methods: A retrospective analysis was conducted on the medical records of 1343 AD patients admitted between 2011 and 2024. Statistical descriptions were performed for baseline characteristics, clinical manifestations, imaging classification, treatment, and outcomes. Univariate and multivariate logistic regression analyses were employed to identify independent risk factors for in-hospital mortality. Results: Among the 1,343 patients, 82.7% were male, with a mean age of 52.7 ± 12.4 years; 71.3% had hypertension. Stanford type A and type B AD accounted for 41.7% and 58.3%, respectively. Acute onset was observed in 76.5% of patients, with chest pain (66.4%) being the most common symptom. The onset of AD showed seasonal (peak in winter, especially December) and diurnal (76.6% of cases presented between 12:00 and 23:00) clustering trends. The rate of surgery was 62.0%, showing an increasing trend over the years. The overall mortality rate was 10.0% (95% CI: 8.4%-11.8%), with type A mortality (16.9%, 95% CI: 14.2%-19.9%) significantly higher than that of type B (4.0%, 95% CI: 2.7%-5.7%). Multivariate analysis identified acute onset (OR = 3.484),chest pain (OR = 1.658), increased heart rate (OR = 1.017), Stanford type A (OR = 3.959) and larger false lumen diameter (OR = 1.357) as independent risk factors for in-hospital mortality (all Conclusion: This study indicates that AD predominantly affects middle-aged and elderly males with hypertension, with distinct temporal and seasonal patterns. Acute onset, chest pain, type A dissection, higher heart rate, non-surgical, and larger false lumen diameter significantly increase the risk of in-hospital mortality, highlighting the need for increased vigilance in emergency clinical practice.
