1 · What the graph read from it

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.

2 · The registry

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 a common complication in orthopaedic patients; however, their risk factors and temporal patterns remain incompletely understood. This study aimed to identify factors associated with inpatient falls and to characterize the timing and circumstances of falls during hospitalization.

methodsA retrospective cohort study was conducted including 1,617 consecutive orthopaedic inpatients. Univariate logistic regression analysis was performed in the full cohort using variables available for all patients. Propensity score matching (1:1) was then performed using age, sex, and body mass index. Additional clinical variables, including medication-related factors, were evaluated in the matched cohort. Multivariate logistic regression analysis was performed to identify independent risk factors. Fall characteristics, including timing and location, were descriptively analyzed.

resultsAmong 1,617 patients, 48 (3.0%) experienced falls during hospitalization. In the full cohort, age was significantly associated with falls, whereas other baseline variables were not. Propensity score matching yielded 48 matched pairs with well-balanced baseline characteristics. In the matched cohort, the number of medications was significantly higher in the fall group and remained independently associated with falls (adjusted OR 1.14, 95% CI 1.01-1.29, p = 0.036). Falls most frequently occurred in patient rooms (56.3%) and were observed across all time periods. Falls occurred more frequently in the early phase of hospitalization, with 70.8% occurring within the first 14 days.

conclusionsA higher number of medications was independently associated with inpatient falls in orthopaedic patients. Falls occurred most frequently in the early phase of hospitalization, particularly on the day of admission and the following day. These findings suggest that early targeted interventions and careful medication management may help reduce inpatient falls.
