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

backgroundEmerging evidence has demonstrated that either laparoscopic-assisted gastrectomy (LAG) or robotic-assisted gastrectomy (RAG) could be adopted as standard treatment for early gastric cancer. However, the long-term survival and recurrence rate after LAG or RAG for locally advanced gastric cancer (AGC) has seldom been reported.

methodsWe retrospectively analyzed the data from 339 patients who underwent LAG and 163 patients who underwent RAG from a prospectively established database in the Chinese People's Liberation Army General Hospital. We compared the short- and long-term oncological outcomes of the RAG group versus the LAG group in the entire cohort, and in a propensity score-matched cohort.

resultsBefore propensity score matching (PSM), the two groups revealed comparable 3-year overall survival rates (OS, RAG vs. LAG: 76.1 vs. 81.7%, p = 0.118), and recurrence-free survival rates (RFS, RAG vs. LAG: 73.0 vs. 67.6%, p = 0.297). Similar results were obtained in the propensity score-matched cohort; the respective overall survival rates in the propensity score-matched RAG and LAG groups were 76.1 and 79.8% (p = 0.552), and the respective RFS rates were 73.0 and 68.7% (p = 0.386). After PSM, RAG was still associated with a significantly longer mean operating time (249.46 ± 63.26 vs. 232.17 ± 65.39 min, p = 0.008) and higher total costs (133.38 ± 41.62 vs. 95.34 ± 29.39 10

conclusionAlthough there were some differences in the outcomes of RAG versus LAG in AGC patients, both RAG and LAG were similar in short-term recovery and long-term oncological outcomes.
