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

backgroundLaparoscopic gastrectomy is an acceptable procedure for early-stage gastric cancer; however, most patients are diagnosed at an advanced stage and older age in Taiwan. The feasibility and safety of applying laparoscopic gastrectomy in daily practice remain unclear. This study aimed to examine the short- and long-term outcomes of laparoscopic gastrectomy versus open procedures.

methodsFrom 2007 to 2015, 192 patients who underwent open gastrectomy and 189 patients who underwent laparoscopic gastrectomy for gastric cancer at a single center were included. Propensity score matching analysis was used to adjust selection biases associated with age, preoperative hemoglobin, the extent of resection, tumor size, and stage of the disease. The demographics, perioperative parameters, short-term postoperative results, and 5-year survival data were analyzed.

resultsOpen gastrectomy was more frequently performed in the elderly, larger tumor size, advanced stage of the disease, and disease requiring total gastrectomy or combined organ resection. After propensity score matching, 108 patients with laparoscopic gastrectomy were compared to 108 patients with open gastrectomy. The morbidity rates were not different in both groups (25.9%), while hospital stay was shorter in the laparoscopic group (16.0 vs. 18.8 days, p = 0.04). The 5-year overall survival and disease-free survival were superior in the laparoscopic group (p = 0.03 and p = 0.01, respectively); however, the survival differences were not significant in the subgroup analysis by stage. Laparoscopic gastrectomy had fewer recurrences than open gastrectomy. The pattern of recurrence was not different between the groups.

conclusionsLaparoscopic gastrectomy can be safely applied in both early and locally advanced gastric cancer without compromising oncologic outcomes.
