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

purposeIntroduction of three-dimensional (3D) display might remove technical obstacles of laparoscopic surgery and improve laparoscopic skills. We analyzed the effect of 3D technology on operative performance during laparoscopic total gastrectomy (LTG) for gastric cancer and assessed its advantages over two-dimensional (2D) laparoscopy.

methodsThis study included 30 consecutive surgeries of LTG with esophagojejunostomy by the overlap method performed (3D group, n = 15, 2D group, n = 15). The surgical outcomes were compared between the 3D and 2D groups. Further, we compared the performance time, the frequency of bleeding requiring hemostasis, and the frequency of remaking the surgical view by the assistant's forceps in each laparoscopic scene between the 3D and 2D groups.

resultsAll surgeries were completed without any complications. The total time of pure laparoscopic scenes was shorter in the 3D than 2D group (154.2 vs. 182.7 min, P = 0.026), and total blood loss was almost the same (10 vs. 20 g, P = 0.195). The operative time during lymphadenectomy in scenes 6 and 7 were significantly shorter in the 3D than the 2D group (scene 6, 13.5 vs. 17.5 min, P = 0.003, and scene 7, 12.4 vs. 18.4, P = 0.025) and esophagojejunostomy (30.3 vs. 39.4 min, P = 0.008). The frequency of tissue exposure by the assistant was significantly less in the 3D group than the 2D group in scenes 6 and 7 (scene 6, n = 3.0 vs. 4.0, P = 0.006, and scene 7, n = 3.0 vs. 4.0, P = 0.017).

conclusions3D display is useful due to improvement of surgical skill during difficult situations such as lymphadenectomy around the celiac artery, which requires handling in the tangential view, and reconstruction using the suturing technique in a narrow space.
