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
purposePostoperative complications continue to be a principal cause of morbidity following surgeries for colorectal cancer.
methodsThis retrospective cohort study comprising 296 patients who underwent elective resections between 2014 and 2018 examined the influence of perioperative hyperglycemia, nutritional recovery, and the duration of diabetes on postoperative outcomes. Blood glucose levels were documented across the preoperative, intraoperative, and postoperative periods and categorized into four ranges (< 70, 70-119, 120-180, > 180 mg/dL). Nutritional recovery was characterized by the time to initial oral intake and resumption of a regular diet. Complications were classified using the Clavien-Dindo system, occurring in 14.5% of the cohort, with major complications (grades III-V) in 10.4% and a mortality rate of 0.3%.
resultsThe primary outcome of this study was the occurrence of complications classified as grade II or higher according to the Clavien-Dindo system, which served as the basis for all multivariable analyses. Postoperative hyperglycemia was correlated with a significantly increased rate of complications (26.3% vs. 14.0%, p = 0.049) and an extended duration of hospitalization (10.0 ± 4.0 vs. 7.0 ± 4.0 days, p < 0.001). Logistic regression analysis identified postoperative hyperglycemia (OR 2.10, 95% CI 1.15-3.85, p = 0.016) and a delayed transition to a regular diet (OR 1.95, 95% CI 1.02-3.72, p = 0.041) as independent predictors of complications of grade II or higher. Each additional year of diabetes duration was associated with a 10.4% increase in risk (OR 1.104, 95% CI 1.021-1.194, p = 0.012).
conclusionThese results underscore the integral role of glycemic and nutritional considerations in influencing postoperative recovery. Incorporating postoperative hyperglycemia control, prompt nutritional recovery, and diabetes duration into perioperative risk assessment may optimize ERAS protocols and lessen morbidity in colorectal cancer surgical interventions.
