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

backgroundRobot-assisted colorectal surgery (RAS) is increasingly adopted; however, surgeon workload during supervised training and its determinants remain unclear.

methodsWe conducted a single-center study combining a prospective surgical task load index (Surgical-TLX) assessment and a retrospective cohort analysis (October 2023-August 2025). Junior surgeons were defined as non-Japan Society for Endoscopic Surgery (JSES)-certified surgeons who had < 10 robot-assisted colorectal cases as the primary operator and were within 8 years after graduation. All junior cases were performed under direct supervision by JSES-certified surgeons throughout the procedure. The primary outcome was Surgical-TLX workload (six domains). Secondary outcomes included operative time, console time, blood loss, Clavien-Dindo complications, length of stay, and pathological findings.

resultsSurgical-TLX was assessed in 72 cases by 10 surgeons. Compared with JSES-certified surgeons, junior surgeons had higher mental, temporal, task complexity, and situational awareness workload. In multivariable models, high temporal burden was associated with advanced tumor factors (T ≥ 3 and N-positive disease). Operative and console times were longer for junior surgeons, whereas blood loss, postoperative complications (Clavien-Dindo ≥ 2 or ≥ 3), length of stay, and pathological outcomes were comparable.

conclusionsUnder structured supervision, RAS can be implemented safely for junior surgeons despite higher perceived workload. Surgical-TLX may help visualize cognitive burden and inform graded autonomy and supervisory strategies, particularly for advanced tumors.
