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

Introduction and Importance: Transdiaphragmatic intercostal hernias (TDIHs) are rare and typically posttraumatic. The coexistence of a TDIH with congenital anomalies, such as a Morgagni hernia (MH) and chest wall defect, is exceptionally uncommon. This report details a unique case of MH associated with an ipsilateral intercostal hernia in an adult, underscoring key diagnostic and surgical challenges. Case Presentation: A 71-year-old man with multiple comorbidities presented with acute abdominal pain and a right-sided chest wall bulge. Computed tomography revealed a large right lateral diaphragmatic and intercostal hernia between the right 9th and 10th ribs, with bowel loops protruding through the intercostal defect. The symptoms spontaneously improved, and repeat imaging showed a reduction of the hernia content. Thoracotomy revealed an omental herniation through an anteromedial diaphragmatic defect (MH) and a congenital chest wall defect with stretched intercostal muscles. The MH was primarily repaired using nonabsorbable sutures, and rib approximation was performed with absorbable sutures to address the chest wall defect. Clinical Discussion: This case is remarkable for the association of two congenital defects: an MH and a TDIH. Unlike typical posttraumatic TDIHs, the intercostal defect in this case stemmed from congenital chest wall maldevelopment. Preoperative diagnosis was challenging, with the MH initially missed on imaging. This emphasizes the importance of considering congenital variants in atypical hernias. Conclusion: To our knowledge, this is the first documented case of a TDIH occurring in conjunction with an MH, both likely congenital. Prompt recognition and tailored interventions are crucial for avoiding missed diagnoses and complications.
