Case Report: Diagnostic pitfalls and laparoscopic repair of a delayed large right-sided traumatic diaphragmatic hernia.
Article in Frontiers in surgery, 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
Background: Delayed right-sided traumatic diaphragmatic hernia (TDH) may be overlooked during polytrauma assessment because concomitant injuries dominate attention and the liver can obscure diaphragmatic discontinuity. Subsequent respiratory and gastrointestinal symptoms may remain nonspecific until obstruction or visceral compromise develops. Case description: A 50-year-old man presented with more than 20 h of nausea and vomiting 19 months after severe blunt trauma. Since the injury, he had experienced intermittent dyspnea, chest tightness, postprandial fullness, abdominal distension, and abdominal pain. His admission oxygen saturation was 94%, with no supplemental oxygen recorded. Examination revealed diminished right-sided breath sounds and bowel sounds in the lower right hemithorax. Computed tomography demonstrated discontinuity of the right hemidiaphragm and herniation of the stomach, liver, gallbladder, and hepatic flexure. Transabdominal laparoscopy confirmed an approximately 8.0 cm×15.0 cm posterolateral defect. After adhesiolysis, all herniated organs were reduced and remained viable. The defect was closed primarily without mesh because the mobilized edges were robust and could be approximated without a residual gap, visible tearing, or excessive tension. Respiratory and gastrointestinal symptoms resolved, and early postoperative imaging confirmed restoration of the abdominal viscera below the diaphragm. Conclusion: After high-energy trauma, discordant respiratory and meal-related symptoms plus intrathoracic bowel sounds should prompt targeted multiplanar CT review. In selected stable patients, transabdominal laparoscopy can combine reduction, assessment of visceral viability, and repair. The approach and need for reinforcement should be individualized according to adhesions, tissue quality, and achievable edge approximation.
