Rationales for Prehabilitation Programs in Patients Preparing for Oncologic Surgery: A Systematic Review.
Synthesis in Annals of surgical oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundPrehabilitation aims to improve patients' resilience to surgery and enhance postoperative recovery. Understanding rationales for prehabilitation content may identify opportunities for program optimization. This systematic review provides an overview of rationales, intervention, and outcomes used in prehabilitation studies in oncological populations. PATIENTS AND
methodsWe searched the databases MEDLINE, Embase, and Scopus on 1 March 2024. Comparative prehabilitation studies including patients undergoing oncological surgery were included. Prehabilitation was defined as a preoperative exercise program, alone or combined with other components, with the explicit aim of improving postoperative outcomes. Extracted outcomes included reported rationales, program content, and primary endpoints.
resultsIn total, 140 studies (N = 24,925 patients) were included. Most (N = 125, 89%) reported a rationale for improving physical fitness, particularly cardiorespiratory fitness (N = 97, 69%). Psychological (N = 46, 33%) and metabolic (N = 28, 20%) rationales were reported less frequently. Rationales for specific attributes (e.g., intensity) were rarely described. Exercise was predominantly supervised (N = 57, 41%), and of these supervised sessions, most were prescribed three times per week (N = 25, 44%). Almost all studies (N = 121, 86%) included anaerobic exercise component at moderate-intensity continuous (N = 39, 32%) or high-intensity interval (N = 34, 28%) mode. Intended duration varied from 1 to 12 weeks. Most reported primary endpoints were surgical outcomes (e.g., complications) (N = 59, 42%), although definitions varied.
conclusionsPreoperatively improving physical fitness is a widely used rationale for prehabilitation; however, studies are implicit in rationales for specific program components. Content and duration of prehabilitation showed considerable variation, often determined by feasibility and time to surgery. Prehabilitation studies could benefit from standardized outcomes. Adopting a more mechanistically grounded approach could improve program design and possibly effectiveness.
