Association of the Flemish Triage Risk Screening Tool with postoperative outcomes in older adults after colorectal cancer surgery: retrospective cohort study.
Observational study in BJS open, 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
backgroundOlder adults undergoing colorectal cancer (CRC) surgery are at increased risk of postoperative complications, mortality, and loss of independence. Frailty screening tools may support perioperative risk stratification. This study evaluated the association between the Flemish Triage Risk Screening Tool (fTRST) and postoperative outcomes.
methodsThis retrospective multicentre cohort study analysed the Emilia-Romagna Surgical Colorectal Audit. Patients aged ≥ 70 years undergoing CRC surgery (2019-2023) were included. Patients with fTRST scores ≥ 2 and < 2 were matched 1 : 1 using propensity score matching. Primary outcomes were 30-, 90-, and 180-day mortality and complications. Secondary outcomes included prolonged hospital stay and discharge to a non-independent setting. Logistic regression and receiver operating characteristic (ROC) curve analyses were performed.
resultsIn all, 1539 patients were included in the study. Mortality at 30, 90, and 180 days was 4.2%, 7.1%, and 10.5%, respectively. In the unmatched cohort, each 1-point increase in fTRST score was significantly associated with 30-day mortality (odds ratio (OR) 1.36; 95% confidence interval (c.i.) 1.12 to 1.66), complications (OR 1.12; 95% c.i. 1.02 to 1.23), prolonged hospital stay (OR 1.13; 95% c.i. 1.03 to 1.24), and discharge to a non-independent setting (OR 1.35; 95% c.i. 1.21 to 1.51). After matching 566 pairs, higher fTRST score remained significantly associated with 30-day mortality (OR 1.33; 95% c.i. 1.09 to 1.63) and discharge to a non-independent setting (OR 1.40; 95% c.i. 1.25 to 1.59). ROC analysis using an fTRST cut-off of ≥2 showed moderate discrimination for 30-day mortality and discharge to a non-independent setting, with areas under the ROC curve of 72.4% (negative predictive value 98.2%) and 67.2% (positive predictive value 66.3%), respectively.
conclusionsThe fTRST is a simple screening tool for identifying older adults at risk of adverse postoperative and functional outcomes after CRC surgery, supporting perioperative planning.
