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 proximal gastrectomy (LPG) is performed as a function-preserving surgery for patients with early proximal gastric malignant tumors; however, whether LPG has advantages postoperatively compared with laparoscopic total gastrectomy (LTG) is debatable, especially with regard to nutritional outcomes.

methodsWe evaluated 20 patients who underwent LTG and 10 patients who underwent LPG with double tract reconstruction (LPG-DT) who were diagnosed preoperatively with T1a or T1b N0 Stage IA gastric cancer in our department in the same time period. The statistical relevance of complications, surgical maneuvers, clinical factors and changes in weight, skeletal muscle index (SMI) and serum albumin levels after surgery was compared between the LPG-DT group and the LTG group.

resultsNo differences between groups were observed in patient demographics, operation time, blood loss, complications, number of dissected lymph nodes and pathological stage. The body weight reduction rate was significantly lower in the LPG-DT group compared with the LTG group at 6 months (5.7 vs. 14.9%, respectively; p = 0.0045) and 1 year after surgery (9.6 vs. 17.9%, respectively; p = 0.0042). The SMI reduction rate of the LPG-DT group in the first postoperative year was significantly lower than that of the LTG group (9.3 vs. 18.3%, respectively; p = 0.0057).

conclusionsPatients with early gastric cancer who underwent LPG-DT had acceptable morbidity and mortality, similar to those who underwent LTG. Body weight and SMI reduction rates were lower in the LPG-DT group than in the LTG group. Thus, LPG-DT is an appropriate procedure for patients with clinical Stage IA proximal gastric cancer.
