Risk Factors for Severe Postoperative Complications After Laparoscopic Colorectal Cancer Surgery in Octogenarians: A Retrospective Cohort Study.
Article in Clinical interventions in aging, 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
Purpose: To evaluate the incidence and risk factors of severe postoperative complications in patients aged ≥80 years undergoing laparoscopic colorectal cancer surgery. Patients and Methods: Patients aged ≥80 years who underwent laparoscopic colorectal cancer surgery between February 2007 and September 2018. Severe complications were defined as Clavien-Dindo grade III or higher. Univariate and multivariate logistic regression analyses were performed to identify risk factors. Results: Among 170 patients, 26 (15.3%) experienced severe postoperative complications. Gastrointestinal events were most common (8.0%), followed by respiratory (3.5%) and cardiovascular (2.9%) complications. Two patients (1.2%) died postoperatively. Multivariate analysis identified estimated blood loss >100 mL (OR = 4.53, 95% CI: 1.75-11.70, Conclusion: Severe complications occurred in 15.3% of octogenarians undergoing laparoscopic colorectal cancer surgery. Age ≥85 years and intraoperative blood loss >100 mL were independent risk factors. Preoperative anemia and ASA III were borderline predictors. These factors may aid in perioperative risk stratification and surgical decision-making in elderly patients.
