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

introductionNutcracker syndrome is a rare vascular condition whose management has long been controversial. Data remain scarce in Sub-Saharan Africa. The objective of this study is to report the clinical presentations and mid-term outcomes of patients who underwent surgical treatment for Nutcracker syndrome in Benin.

methodsThis was a single-center retrospective study conducted from November 2022 to January 2025. It included all patients who underwent surgical management of Nutcracker syndrome at our hospital during this period.

resultsSix cases of Nutcracker syndrome were identified, all in male patients. The median age was 15.5 years [IQR: 13.5-16]. Left flank pain and varicocele were present in all patients. Abdominal Doppler ultrasound and abdominal CT angiography were performed in all cases. The mean aorto-mesenteric angle was 11.8° ± 2.7. The surgical procedure performed was transposition of the left renal vein into the inferior vena cava. Postoperative outcomes were satisfactory, with complete resolution of symptoms and no major complications or deaths during a median follow-up of 9 months [IQR: 8-13].

conclusionsSurgery for rare vascular anomalies is feasible in Sub-Saharan Africa with excellent results. This supports advocacy for improved technical infrastructure.
