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
introductionAbbreviating preoperative fasting improves clinical outcomes, such as reducing hospital stay, morbidity and postoperative mortality. However, there is a lack of data regarding the reduction of hospital costs. Therefore, the objective of the research was to analyze whether reducing preoperative fasting time with the provision of carbohydrate-rich liquid has an influence on hospital costs for surgical patients.
methodsRetrospective data were collected from patients undergoing surgical procedures at a University Hospital in 2019. The main outcome variable investigated was cost hospital in reais. Data such as gender, age, type of surgery, length of stay, nutritional data, and outcomes were also collected. Next, a comparative analysis of the variables was carried out in relation to patients who followed the preoperative fasting abbreviation protocol, with liquid rich in carbohydrates, and those whose protocol was not applied.
resultsThe mean (± standard deviation) fasting time of the study participants was 267.92±89.8 (range: 120-605) minutes in the group that shortened the fast and 768.6±247.8 (150 -1244) minutes in the group that did not perform the abbreviation (p<0.01). In relation to hospital costs, it was observed that patients who shortened their fasting had a lower average cost than those who did not shorten it (R$ 3,245.37±4,157.5 vs R$ 10,897.39±16,701.3; p< 0.01). They were shown to be significantly associated with higher cost, malnutrition and prolonged preoperative fasting.
conclusionsAccording to data from this study, shortening preoperative fasting reduces hospital costs. Corroborating prolonged fasting, malnutrition also makes hospitalization more expensive.
