Effect of different surgical approaches on the survival and safety of Siewert type II esophagogastric junction adenocarcinoma: a systematic review and meta-analysis.
Synthesis in BMC cancer, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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
backgroundWhether a transthoracic (TT) procedure by a thoracic surgeon or a transabdominal (TA) by a gastrointestinal surgeon is best for Siewert type II esophagogastric junction adenocarcinoma (EGJA) remains unknown. Survival and perioperative outcomes were compared between the two groups in this meta-analysis to clarify this argument.
methodsWe searched 7 databases for eligible studies comparing TT and TA procedures for Siewert type II EGJA. The final analyzed endpoints included intraoperative and hospitalization outcomes, recurrence, complication, and survival.
resultsSeventeen studies involving 10,756 patients met the inclusion criteria. The TA group had higher rates of overall survival (OS) (HR: 1.31 [1.20 ~ 1.44], p < 0.00001) and disease-free survival (DFS) (HR: 1.49 [1.24 ~ 1.79], p < 0.0001). The survival advantage of OSR and DFSR increased with time. Subgroup analysis of OS and DFS suggested that TA remained the preferred approach among all subgroups. More total/positive lymph nodes were retrieved, and fewer lymph node recurrences were found in the TA group. The analysis of perioperative outcomes revealed that the TA procedure was longer, had more intraoperative blood loss, and prolonged hospital stay. Similar R0 resection rates, as well as total recurrence, local recurrence, liver recurrence, peritoneal recurrence, lung recurrence, anastomosis recurrence and multiple recurrence rates, were found between the two groups. The safety analysis showed that the TT procedure led to more total complications, anastomotic leakages, cases of pneumonia, and cases of pleural effusion.
conclusionsThe TA procedure appeared to be a suitable choice for patients with Siewert type II EGJA because of its association with longer survival, fewer recurrences, and better safety.
