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

aimTo compare short- and long-term outcomes of laparoscopy-assisted and open distal gastrectomy for gastric cancer.

methodsA retrospective study was performed by comparing the outcomes of 54 patients who underwent laparoscopy-assisted distal gastrectomy (LADG) with those of 54 patients who underwent open distal gastrectomy (ODG) between October 2004 and October 2007. The patients' demographic data (age and gender), date of surgery, extent of lymphadenectomy, and differentiation and tumor-node-metastasis stage of the tumor were examined. The operative time, intraoperative blood loss, postoperative recovery, complications, pathological findings, and follow-up data were compared between the two groups.

resultsThe mean operative time was significantly longer in the LADG group than in the ODG group (259.3 ± 46.2 min vs 199.8 ± 40.85 min; P < 0.05), whereas intraoperative blood loss and postoperative complications were significantly lower (160.2 ± 85.9 mL vs 257.8 ± 151.0 mL; 13.0% vs 24.1%, respectively, P < 0.05). In addition, the time to first flatus, time to initiate oral intake, and postoperative hospital stay were significantly shorter in the LADG group than in the ODG group (3.9 ± 1.4 d vs 4.4 ± 1.5 d; 4.6 ± 1.2 d vs 5.6 ± 2.1 d; and 9.5 ± 2.7 d vs 11.1 ± 4.1 d, respectively; P < 0.05). There was no significant difference between the LADG group and ODG group with regard to the number of harvested lymph nodes. The median follow-up was 60 mo (range, 5-97 mo). The 1-, 3-, and 5-year disease-free survival rates were 94.3%, 90.2%, and 76.7%, respectively, in the LADG group and 89.5%, 84.7%, and 82.3%, respectively, in the ODG group. The 1-, 3-, and 5-year overall survival rates were 98.0%, 91.9%, and 81.1%, respectively, in the LADG group and 91.5%, 86.9%, and 82.1%, respectively, in the ODG group. There was no significant difference between the two groups with regard to the survival rate.

conclusionLADG is suitable and minimally invasive for treating distal gastric cancer and can achieve similar long-term results to ODG.
