1 · What the graph read from it

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.

2 · The registry

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

purposeAs the population ages, the demand for surgery in the elderly is increasing. This study aimed to evaluate the safety, short-term, and oncological outcomes of robot-assisted surgery for colorectal cancer in patients aged ≥ 85 years.

methodsWe retrospectively analyzed 817 patients who underwent robotic surgery for colorectal cancer at seven institutions between 2016 and 2025. Patients were divided into an elderly group (≥ 85 years, n = 52) and a non-elderly group (< 85 years, n = 765). Propensity score matching was used to balance the baseline characteristics, resulting in 52 matched patients per group.

resultsAfter matching, no significant differences were observed in operative time (238 vs. 255 min, p = 0.198), blood loss (18 vs. 10 mL, p = 0.740), or the number of retrieved lymph nodes (15 vs. 16, p = 0.977). Postoperative complication rates (Clavien-Dindo grade ≥ II) were comparable between the elderly and non-elderly groups (9.6% vs. 13.5%, p = 0.760). Furthermore, the 3-year recurrence-free survival (100% vs. 96.1%, p = 0.482) and overall survival (88.1% vs. 95.6%, p = 0.244) were not significantly different between the groups.

conclusionsRobotic surgery for colorectal cancer is safe and feasible in carefully selected patients aged ≥ 85 years. Surgical indications should be determined based on individualized assessments rather than chronological age alone.
