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.
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
backgroundThe surgical approach for esophagogastric junction cancers (EJC), Siewert II, has been controversial regarding margin control, reconstruction, and lymphadenectomy extension. Therefore, predicting the need for total/subtotal esophagectomy and proximal gastrectomy (TEPG) or total gastrectomy with distal esophagectomy (TGDE) can be challenging, with each direction usually excluding the other. Historically, complication rates for TEPG are higher, affecting further systemic treatment and long-term outcomes.
aimsThe aim of this study was to describe a surgical strategy for approaching tumors such as Siewert II EGJ, with the intraoperative decision to perform total gastrectomy with lymphadenectomy D2 or esophagectomy with lymphadenectomy based on intraoperative frozen sections.
methodsAll patients underwent laparotomy, beginning with greater curvature detachment while preserving the right gastroepiploic, right and left gastric arteries; dissection of the esophageal hiatus for node harvesting; and transection of the distal esophagus and its frozen section. TGDE was preferred if the proximal margin of the distal esophagus was negative; TEPG and gastric tube reconstruction were performed through transhiatal access if the margin was positive.
resultsAmong 38 Siewert II patients, 26 (69%) underwent TGDE and 12 (31%) underwent TEPG, regardless of the trend toward higher complication rates, positive margins, and shorter overall survival in the TEPG group, no statistically significant differences were detected.
conclusionsAlthough no significant differences in morbidity between the two procedures were noted, type II errors could be a possible cause. This study suggests that unnecessary esophagectomies can be avoided without jeopardizing surgical or oncologic outcomes by opting for a less morbid procedure.
