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

Background: The rising incidence of rectal cancer (RC) in elderly patients contrasts with the scarcity of robust evidence comparing robotic-assisted and laparoscopic resection in this population. This study evaluated clinical outcomes and quality-of-life (QoL) metrics between these approaches in elderly patients with mid-low RC. Methods: Consecutive patients aged 70 years or older with mid-low RC who underwent minimally invasive resection at two tertiary centers from January 2017 to December 2024 were categorized into robotic (n=211) and laparoscopic (n=812) cohorts. Outcomes were analyzed using inverse probability of treatment weighting (IPTW) based on propensity scores. Results: After IPTW, the effective sample comprised 2036 patients (1012 robotic group, 1024 laparoscopic group) with balanced clinicopathological characteristics. After matching, the pure operation time was comparable between groups ( Conclusions: Robotic-assisted surgery is a safe and feasible alternative for elderly patients with mid-low RC, offering reduced perioperative complications, superior functional preservation, and potential CSS benefits in T4 disease.
