Changes in Functional Capacity and Body Composition After a Multimodal Prehabilitation Program in Patients with Cancer undergoing Abdominal Surgery.
Article in Annals of surgical oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundPreoperative functional capacity and body composition are associated with postoperative outcomes in patients undergoing abdominal surgery for cancer. Long-term effects of multimodal prehabilitation and exercise dose-response associations remain unclear. This study aimed to investigate changes in functional capacity and body composition during and after prehabilitation and evaluate exercise dose-response associations.
methodsData from 816 patients who participated in the monocenter stepped wedge F4S PREHAB trial (March 2021-April 2024) and underwent elective abdominal surgery for gastrointestinal, gynecological, or urological cancers were included. Functional capacity measures included estimated peak oxygen uptake, maximum short exercise capacity, muscle strength (leg press, handgrip), and five-times sit-to-stand test. Body composition measures included weight, fat-free mass, percentage body fat, and phase angle. Assessments occurred at baseline, after prehabilitation, and 3 months postoperatively. Changes over time and dose-response associations were evaluated with linear mixed models.
resultsMaximum proportions of missing data ranged from 12.9% at preintervention and 24.9% at postintervention to 62.4% after surgery. Significant improvements over time were observed in estimated peak oxygen uptake (β=0.6 mL/kg/min, 95% confidence interval [CI] 0.4-0.8), maximum short exercise capacity (β=17.5 Watt, 95% CI 13.8-21.2), leg press (β=18.9 kg, 95% CI 15.9-21.9), handgrip (β=1.1 kg, 95% CI 0.6-1.6), sit-to-stand time (β=0.9 seconds, 95% CI -1.1 to -0.6), body weight (β=1.1 kg, 95% CI 0.7-1.4), and fat-free mass (β=0.5 kg), 95% CI 0.1-0.8). Some exercise dose-response associations were found. Functional capacity measures returned to or declined below baseline value. Sensitivity analyses with complete data at follow-up yielded comparable findings with attenuated associations. Associations varied by tumor type, neoadjuvant therapy, malnutrition risk, and training compliance.
conclusionsFunctional capacity and body composition improved after prehabilitation, although gains were generally not sustained postoperatively. Associations may vary between patient subgroups. Future research should focus on targeted approaches and integration with improved postoperative rehabilitation.
