Renal Artery Stenosis Secondary to Cytomegalovirus Infection in an Infant.

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
backgroundRenal artery stenosis is an uncommon cause of secondary hypertension in infants and is rarely related to infectious etiologies such as cytomegalovirus (CMV). CASE SUMMARY: We report a 5-month-old infant who was admitted for afebrile status epilepticus and found to have severe hypertension. Imaging revealed focal stenosis of the right renal artery. Virological investigations confirmed active CMV infection. The patient was treated with intravenous ganciclovir, leading to normalization of blood pressure and complete radiological resolution of the stenosis within 6 weeks. DISCUSSION: CMV has a known endothelial tropism and may induce inflammatory vascular lesions. Renal artery involvement outside the transplant setting is exceptionally rare. This case highlights a reversible inflammatory vasculopathy related to CMV infection. TAKE-HOME MESSAGES: CMV infection should be considered in infants presenting with unexplained renal artery stenosis. Early antiviral therapy may lead to complete reversibility without invasive intervention.
