Multimodal prehabilitation for upper gastrointestinal tumors: effects on postoperative morbidity and mortality - a meta-analysis of randomized controlled trials.

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: Patients suffering from upper gastrointestinal (UGI) cancers often present with malnutrition and frailty before undergoing major surgical procedures, which significantly elevates the risk of postoperative complications. Prehabilitation focuses on optimizing a patient's functional capacity before surgery to improve postoperative outcomes. Our goal was to synthesize the effects of prehabilitation on the postoperative outcomes of UGI cancer patients undergoing major surgical intervention using a systematic review and meta-analysis. Methods: A comprehensive systematic search was conducted across the PubMed, Embase, Cochrane, and Scopus databases to identify relevant randomized controlled trials (RCTs). Ten RCTs, encompassing data from 878 patients, were included in the analysis. Pooled risk ratios (RRs) were calculated for dichotomous variables (e.g., incidence of complications), and weighted mean differences were calculated for continuous variables using a random-effects model. Study quality was assessed using the RoB2 and GRADE approaches. Results: The meta-analysis showed a trend toward a lower incidence of minor postoperative complications (Clavien-Dindo Grade I-II) in the prehabilitation group. While the common effect model showed significance, the certainty of evidence remains low to very low for most outcomes, suggesting these results should be interpreted with caution. However, a significant reduction was found in Grade III complications when using a common effect model, although no significant differences were detected in Grade IV complications or mortality. Cardiovascular complications and hospital readmission rates also showed no significant disparity. Conclusion: The implementation of prehabilitation in UGI cancer patients is safe and shows a positive trend toward reducing minor postoperative complications, thereby enhancing patient comfort and potentially accelerating recovery time. While the certainty of evidence remains low, further high-quality RCTs with larger patient cohorts are warranted, especially to explore the role of multimodal prehabilitation.
