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

purposeRecently, submucosal tumors (SMTs) of the esophagus have been treated with peroral endoscopic tumor resection (POET) and a new procedure called thoracoscopic endoscopic cooperative surgery (TECS). This study aimed to validate the treatment strategy for SMTs and determine whether or not TECS is a viable option when POET is not feasible.

methodsPOET and TECS were performed in 12 patients between February 2020 and January 2024. The clinical characteristics and perioperative outcomes were retrospectively evaluated.

resultsSix patients were included in each group, with most of the tumors located in the middle thoracic esophagus (75%). The general anesthesia duration was significantly longer in the TECS group than in the POET group (P < 0.001), but no significant differences in endoscopic procedure time, tumor mass index, oral intake date, or length of hospital stay were observed between the two groups. En bloc and R0 resections were performed in all patients. One patient in the TECS group experienced a Clavien-Dindo grade 3a adverse event, and no tumor recurrence occurred during the median follow-up period of 33 (range, 6-53) months.

conclusionTECS is a safe and feasible option for SMTs when POET is difficult to perform.
