Early failure of primary repair of a Bochdalek diaphragmatic defect during retroperitoneal liposarcoma resection: a case report.
Article in Journal of surgical case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Adult Bochdalek hernia is a rare congenital diaphragmatic defect that may complicate the surgical management of retroperitoneal tumors extending into the thoracic cavity. An 87-year-old woman presented with a 24-cm retroperitoneal liposarcoma protruding into the thoracic cavity through a Bochdalek defect. En bloc tumor resection with left nephrectomy and partial diaphragmatic resection was performed. The 5-cm diaphragmatic defect appeared suitable for tension-free primary closure and was repaired with interrupted nonabsorbable sutures. However, on postoperative day 5, acute intrathoracic herniation of the stomach occurred. Reoperation revealed enlargement of the defect to 8 cm, and mesh reconstruction was performed. Chronic stretching of the diaphragm and involvement of the central tendon likely compromised tissue integrity and contributed to early repair failure. Mesh reinforcement should be considered when diaphragmatic defects appear structurally weakened.
