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

purposeWe conducted a prospective clinical control study to identify the best imaging technology among three-dimensional (3-D) high-definition (HD) stereovision and two-dimensional (2-D) ultra-high-resolution (4 K) technology and confirm their effects on surgical outcomes of laparoscopic gastrectomy for gastric cancer.

methodsFrom April 2018 to August 2019, 50 patients were randomly classified into two groups based on the imaging technology (3-D/HD group = 25, 2-D/4 K = 25). After excluding eight patients based on laparoscopic findings, 42 patients were analyzed (3-D/HD group = 21, 2-D/4 K = 21). The primary endpoint was the operative time; the secondary endpoints were blood loss, postoperative infectious complications, and postoperative hospital stay.

resultsThe patients' backgrounds were similar (sex, age, body mass index [BMI], stage, procedure, and extent of lymph node dissection). There were no significant differences in operative time (252 vs. 238 min, P = 0.70), total blood loss, postoperative infectious complications, and postoperative hospital stay between the two groups. However, video analysis of surgeries revealed a significantly shortened median operative time (18 vs. 25 min, P = 0.04) in the suturing step with 3-D/HD; the median number of camera cleaning procedures during suprapancreatic lymph node dissection was significantly lower with 2-D/4 K than with 3-D/HD (n = 4.4 vs. 2.8, P = 0.02).

conclusion3-D/HD and 2-D/4 K laparoscopic radical gastrectomies provide similar surgical outcomes. However, the 3-D monitor reduces suturing time during reconstruction, while the 4 K monitor reduces the number of camera cleaning procedures during lymphadenectomy.
