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

introductionHip fractures are a prevalent type of fracture and a leading cause of disability and mortality among older patients, imposing a substantial burden on both families and society. As surgical intervention is considered the primary means of improving patient outcomes, perioperative optimisation management is essential for enhancing prognosis. A key component of the Enhanced Recovery After Surgery (ERAS) protocol for hip surgery is the innovation of preoperative fasting concepts, which includes the recommendation of preoperative oral carbohydrates for surgical procedures, particularly hip surgery. While preoperative oral carbohydrates have been shown to alleviate hunger and thirst symptoms in patients and promote postoperative recovery, concerns regarding intraoperative aspiration and gastric content retention persist, rendering the safety and feasibility of this approach for surgery a topic of debate. This study aims to investigate and summarise the clinical outcomes of preoperative oral carbohydrates in patients undergoing hip surgery, providing a comprehensive evaluation of their impact on patient recovery and safety. METHODS AND ANALYSIS: A systematic and comprehensive search will be conducted across multiple databases, including CINAHL, PubMed, CNKI, VIP database, Wanfang database, Embase, CBM, Web of Science, Cochrane Central Register of Controlled Trials and ClinicalTrials.gov (https://www. CLINICALTRIALS: gov/), from their inception to November 2024, to identify randomised controlled trials that examine the effect of preoperative oral carbohydrates on patients with hip fractures. The primary outcome of interest will be postoperative insulin sensitivity. The literature search will be screened independently by two researchers to identify eligible articles for inclusion in this meta-analysis. Subsequent data extraction and assessment of risk of bias will be performed. This meta-analysis will provide a comprehensive summary of the available data for each outcome, provided that sufficient data are available. The presence of heterogeneity among the included studies will be evaluated using the χ ETHICS AND DISSEMINATION: This study uses previously published data, and as such, does not require additional ethical approval. The findings will be disseminated through peer-reviewed journals. PROSPERO REGISTRATION NUMBER: CRD42024611468.
