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: Elderly intensive care unit (ICU) patients represent a high-risk group of aspiration. Different feeding patterns will lead to different incidences of aspiration. However, there are few studies on the risk factors of aspiration in elderly ICU patients under different feeding patterns. The aim of this study was to analyze the effects of different eating styles on the occurrence of overt and silent aspiration in elderly ICU patients and to compare the independent risk factors, in order to provide a basis for targeted aspiration prevention. Methods: We retrospectively analyzed the incidence of aspiration in elderly patients admitted to the ICU from April 2019 to April 2022, a total of 348 cases. The patients were divided into the oral feeding group, gastric tube feeding group, and post-pyloric feeding group according to their feeding method. Multi-factor logistic regression was used to analyze the independent risk factors for overt and silent aspiration caused by the different eating patterns of patients. Results: Among the 348 elderly ICU patients included, the overall incidence of aspiration was 72%, with a 22% rate of overt aspiration and a 49% rate of silent aspiration. The overt aspiration rates were 16%, 30%, and 21% in the oral, the gastric tube and the post-pyloric feeding group, respectively; while the silent aspiration rates were 52%, 55%, and 40% in the three groups, respectively. Multiple logistic regression analysis showed that the independent risk factors for both overt and silent aspiration were history of aspiration [odds ratio (OR) =0.075, P=0.004; OR =0.205, P=0.042] and gastrointestinal tumor (OR =0.100, P=0.028; OR =0.063, P=0.003) in the oral feeding group. In the gastric tube feeding group, the independent risk factor for both overt and silent aspiration was the history of aspiration (OR =4.038, P=0.040; OR =4.658, P=0.012). In the post-pyloric feeding group, the independent risk factors for both overt and silent aspiration were mechanical ventilation (OR =0.211, P=0.019; OR =0.336, P=0.037) and intra-abdominal hypertension (OR =0.225, P=0.020; OR =0.329, P=0.032). Conclusions: There were significant differences in the influencing factors and characteristics of aspiration among the elderly patients in the ICU with different feeding patterns. Personalized precautions should be implemented early, so as to reduce the possibility of aspiration.
