Symptomatic subcutaneous emphysema following lumboperitoneal shunt placement: illustrative case.
Article in Journal of neurosurgery. Case lessons, 2025. 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
backgroundSecondary normal pressure hydrocephalus is a common complication in the chronic phase after subarachnoid hemorrhage or intracerebral hemorrhage, with an incidence of approximately 30%. Lumboperitoneal (LP) shunts are often selected for older patients due to their less invasive nature. However, postoperative complications such as infection, catheter malfunction, and subdural hematoma are known. OBSERVATIONS: The authors present the first known case of symptomatic subcutaneous emphysema following LP shunt surgery, necessitating reoperation. The patient was a markedly thin woman (BMI 13.3), and the cause of the complication was determined to be a combination of shallow subcutaneous catheter placement and failure to evacuate retained air prior to closure. LESSONS: In thin patients, LP shunt catheters should be placed in deeper layers to minimize dead space and prevent air retention. In addition, care must be taken to release subcutaneous air before wound closure, especially in procedures performed in the lateral decubitus position. https://thejns.org/doi/10.3171/CASE25584.
