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
backgroundInpatient falls are among the most common adverse events in acute-care hospitals and may result in functional decline, prolonged hospitalization, and increased healthcare costs. However, the characteristics of fall-related fractures and recurrent falls in university hospitals have not been fully investigated.
methodsWe retrospectively reviewed all inpatient fall events reported to the Department of Patient Safety at Niigata University Medical and Dental Hospital between January 2021 and December 2025. Patients younger than 20 years were excluded. Data regarding patient characteristics, mobility status, fracture occurrence, recurrent falls, medication use, and clinical departments were collected from medical records. Univariate and multivariable logistic regression analyses were performed to identify factors associated with fall-related fractures and recurrent falls.
resultsA total of 2571 fall events were identified, yielding an incidence of 2.306 falls per 1000 inpatient-days. Malignant neoplasms were the most common primary diagnosis (36.9%). The incidence of falls was highest in the Departments of Neurology and Neurosurgery. Fall-related fractures occurred in 54 cases (2.1%), most commonly involving the lower extremities, including 17 proximal femoral fractures. Multivariable analysis identified mobility status as the only independent factor associated with fractures (odds ratio [OR], 1.821; 95% confidence interval [CI], 1.263-2.627;
conclusionsPatients with fall-related fractures tended to have relatively high mobility, whereas recurrent falls were associated with reduced mobility, polypharmacy, and central nervous system depressant use. Different characteristics of falls were observed across clinical departments. These findings may help identify patients at high risk for adverse fall-related outcomes and support the development of targeted fall-prevention strategies in university hospitals.
