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

Nutcracker syndrome is a rare condition caused by compression of the left renal vein between the abdominal aorta and the superior mesenteric artery. This results in increased venous pressure, leading to haematuria, flank pain, and pelvic discomfort, particularly in individuals with low body mass index. Diagnosis is often challenging due to nonspecific symptoms and overlap with other pelvic disorders. We report a case of a 49-year-old woman with persistent left flank pain, dysmenorrhea, and recurrent vaginal bleeding. Imaging confirmed compression of the left renal vein. A conservative approach with nutritional support was initially attempted, but due to ongoing symptoms, the patient underwent surgical transposition of the vein with patch angioplasty using bovine pericardium. This case underscores the need to consider Nutcracker syndrome in patients with unexplained haematuria and flank pain, especially in underweight women. We also review current diagnostic tools and treatment options for this uncommon vascular condition.
