Perioperative characteristics and outcomes of colorectal cancer in elderly patients.
Article in World journal of gastrointestinal surgery, 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 cancer (CRC) in older adults presents unique management challenges due to age-related physiological changes and comorbidities. However, this demographic is often underrepresented in clinical research.
aimTo characterise the perioperative features and outcomes of older CRC patients undergoing surgery at a tertiary hospital in Malaysia.
methodsA cross-sectional study was conducted using patient records of older individuals (≥ 65 years old) diagnosed with CRC and who underwent surgery at USM Specialist Hospital, Malaysia, between January 2017 and December 2021. Data on patient characteristics, operative details, pathological findings, body mass index (BMI) based on the Asian classification and postoperative outcomes were collected. Statistical analysis employed
resultsThe study included 98 participants (57.1% males, 82.7% Malay), with the majority aged 65-69 years (44.9%). BMI indicated a significant association with age group (
conclusionBMI, ischaemic heart disease, and metastatic status are critical determinants of survival, highlighting the importance of comprehensive preoperative assessment and individualised management strategies in this vulnerable population. Further larger-scale, longitudinal studies are needed to improve outcomes among older adults with CRC.
