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

backgroundMajor liver surgery is associated with significant physiological stress and a high rate of postoperative complications. Prehabilitation aims to enhance physiological reserve before surgery. Despite the growing volume of liver resections worldwide, the impact of prehabilitation on clinical and economic outcomes in patients undergoing elective liver resection is poorly understood.

methodsA systematic review and meta-analysis was reported in accordance with PRISMA guidelines. MEDLINE, Embase, Web of Science and the Cochrane Library were searched in November 2025. Randomized controlled trials and comparative observational studies evaluating preoperative programs with a structured exercise component, with or without additional nutritional and psychological support in adult patients undergoing major elective liver surgery were included.

resultsSix studies (four RCTs and two comparative cohort studies) comprising 557 patients were included. Prehabilitation resulted in significantly fewer overall postoperative complications (OR 0.55; 95% CI, 0.37 to 0.84; p = 0.005). No significant differences were observed for length of stay (MD -0.38 days; 95% CI, -1.08 to 0.32; p = 0.29), major complications (OR 0.79; 95% CI, 0.50 to 1.27; p = 0.33), mortality (OR 0.40; 95% CI, 0.05 to 3.24; p = 0.39), readmission (OR 0.85; 95% CI, 0.47 to 1.55; p = 0.60) and hospitalization costs (MD = -137.13; 95% CI, -642.19, 367.93; p = 0.59).

conclusionPrehabilitation significantly reduces overall postoperative complications following liver resection. The absence of standardized, liver-specific interventions limits the determination of effective program design. Future research should prioritize standardised protocols and evaluate post-hepatectomy functional recovery, patient-reported outcomes and cost-effectiveness.
