Navigating long-term patient-reported outcomes after colorectal cancer surgery in older adults: ostomy, nutritional status, and living conditions as determinants in a prospective cohort study.
Observational study in International journal of colorectal disease, 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
purposeTo elucidate determinants of long-term patient-reported outcomes (PROs) following colorectal cancer (CRC) surgery in older adults, focusing on the impact of ostomy creation, nutritional status, and living conditions on functional independence and quality of life (QoL).
methodsThis single-center, prospective observational study included patients aged ≥ 75 years who underwent elective CRC resection between July 2020 and December 2023. Comprehensive geriatric assessments were performed preoperatively, and PROs-including Instrumental Activities of Daily Living (IADL), EQ-5D, and EQ-VAS-were reassessed more than one year postoperatively. The primary outcomes were postoperative changes in IADL and QoL. Modified Poisson regression identified independent determinants of long-term decline in each PRO domain.
resultsSixty patients (median age 79 years; 60% female) completed one-year follow-up. IADL declined in 35.6% of patients, EQ-5D in 26.6%, and EQ-VAS in 43.3%. Multivariate analysis revealed that stoma formation was independently associated with IADL decline (adjusted RR = 3.37, 95% CI 1.50-7.54, p = 0.003), whereas living alone postoperatively correlated with preserved IADL (adjusted RR = 0.14, 95% CI 0.02-0.87, p = 0.035). Low preoperative BMI (< 20 kg/m
conclusionAmong older CRC patients, stoma creation predicts long-term functional decline, while low BMI predicts QoL deterioration. Conversely, independent living appears protective for functional maintenance. Integrating PROs into perioperative assessment and tailoring surgical, nutritional, and social interventions may enhance survivorship outcomes in this aging population.
