Prehabilitation and postoperative outcomes in colorectal surgery: an umbrella review.
Review in Journal of anesthesia, analgesia and critical care, 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
backgroundColorectal surgery caries a risk of postoperative morbidity and mortality. Prehabilitation may improve recovery and reduce complications in this population. This umbrella review evaluates the effects of prehabilitation on postoperative outcomes.
methodsGoogle Scholar, PubMed, the Cochrane Library, and HINARI were searched for systematic reviews comparing the effect of prehabilitation with usual care on postoperative complications, length of hospital stays and functional capacity in adults undergoing colorectal surgery. The methodological quality was assessed by using A Measurement Tool to Assess Systematic Reviews (AMSTAR-2). Overlap of primary studies was evaluated using the Corrected Covered Area (CCA), while evidence certainty by Grading of Recommendations, Assessment, Development and Evaluation (GRADE). Heterogeneity was measured using I-squared statistic, and publication bias was examined using funnel plot, Egger's test and Trim and Fill method.
resultsThis umbrella review included 19 systematic reviews with 27,065 participants, most of which were high quality (n = 13; 68.4%). Overall overlap was slight; however, moderate overlap was observed for postoperative complications, length of hospital stay (LOS), and functional capacity. Prehabilitation was associated with a 21% reduction in postoperative complications (risk ratio (RR) = 0.79, 95% CI: 0.69 to 0.89, I
conclusionPrehabilitation in colorectal surgery may reduce postoperative complications, may shorten hospital stay, may improve preoperative and postoperative functional capacity, highlighting faster recovery and improve postoperative quality of life. Findings should be interpreted with caution for the moderate overlap of primary studies, low level certainty, and significant heterogeneity.
