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

backgroundThis retrospective cohort study compared proximal gastrectomy (PG) with double-tract reconstruction (DTR) versus total gastrectomy (TG) with Roux-en-Y reconstruction in terms of clinical outcomes.

methodsAll consecutive patients with upper early gastric cancer (EGC) who underwent PG-DTR or TG in 2008-2016 were selected. TG patients who matched PG-DTR patients in age, sex, body mass index, clinical stage, and ASA score were selected by propensity score matching. Groups were compared in terms of clinicopathological characteristics, clinical outcomes, early (≤ 30 days), late (> 30 days), and severe (Clavien-Dindo grade ≥ III) postoperative complications, 1-year reflux morbidity, recurrence, and mortality.

resultsOf 322 patients, 52 underwent PG-DTR. A matching TG group of 52 patients was selected. The PG-DTR group had smaller tumors (p = 0.02), smaller proximal and distal resection margins (p = 0.01, p < 0.01), and fewer retrieved lymph nodes (p < 0.01). PG-DTR associated with shorter times to diet and hospital stay (both p = 0.02). Groups did not differ in early (11.3 vs. 19.2%, p = 0.19), late (1.9 vs. 5.7%, p = 0.31), or severe complication rates (7.7 vs. 13.5%, p = 0.34). At 1 year, the groups did not differ in reflux symptoms (Visick score) or endoscopic esophagitis (Los Angeles Classification). There were no recurrences. Five-year overall survival rates were 100 and 81.6% (p = 0.02), respectively.

conclusionPG-DTR associated with better clinical outcomes and survival. Complication and reflux rates were similar. PG-DTR may be suitable for upper EGC.
