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

purposeTo address our hypothesis that increased surgical costs for robotic liver resection would be compensated by reduced postoperative care expenses, we compared the economic outcomes of robotic, laparoscopic, and open liver resection under the Japanese national health insurance system.

methodsPatients who underwent liver resection between 2022 and 2024 were included in this study. The perioperative and economic outcomes were compared among the patients who underwent robotic, laparoscopic, and open liver resection using inverse probability of treatment weighting. Subgroup analyses were conducted for single partial resection, mono-segmentectomy, and the resection of two contiguous sections.

resultsOf 402 patients, 302 met the inclusion criteria: robotic (n = 45), laparoscopic (n = 75), and open (n = 182). The hospital revenue per admission did not differ significantly among the three groups (P = 0.427). The overall hospital profit per day was significantly higher in the robotic group than in the laparoscopic and open groups (P < 0.001). The hospital profit per day was more favorable in patients undergoing robotic liver resection for mono-segmentectomy than in those undergoing laparoscopic and open liver resection, and for the resection of two contiguous sections than for open liver resection.

conclusionAlthough the hospital revenue and profit per admission did not differ significantly among the groups, robotic liver resection may offer economic advantages regarding hospital profit per day.
