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

objectiveThere is insufficient evidence to evaluate the long-term outcomes of robotic radical gastrectomy. The aim of this study was to compare the radical results and long-term outcomes of robotic and laparoscopic radical gastrectomy.

methodsWe prospectively collected and retrospectively analyzed the general clinicopathological data of gastric cancer patients treated with robotic radical gastrectomy (RG) and laparoscopic radical gastrectomy (LG) from July 2016 to July 2018 at Fujian Medical University Union Hospital. The RG cohort was matched 1:3 with the LG cohort by using propensity score matching (PSM). The primary endpoints of the study were 3-year overall survival (OS) and 3-year relapse-free survival (RFS).

resultsThe study included 221 patients treated with RG and 1106 patients treated with LG for gastric cancer. After PSM, 211 patients were included in the RG cohort, and 663 patients were included in the LG cohort. The 3-year OS rate was 81.0% in the robotic cohort and 79.3% in the laparoscopic cohort (log-rank test, P = 0.516). The 3-year RFS rate was 78.7% in the robotic cohort and 75.6% in the laparoscopic cohort (log-rank test, P = 0.600). In the subgroup analyses, no significant differences were noted between the RG and LG cohorts in terms of 3-year OS and 3-year RFS (all P > 0.05). The therapeutic value index of each lymph node station dissection in the robotic cohort was comparable to that in the laparoscopic cohort.

conclusionRobotic radical gastrectomy can achieve radical results and long-term outcomes comparable to laparoscopic surgery, and further multicenter prospective studies can be conducted to assess the clinical efficacy of robotic radical gastrectomy.
