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

Left side transposition of the inferior vena cava (IVC) is a rare anatomical variation formed during its complex embryonic developmental process. We present a 71-year-old female patient with an incidentally identified left-sided IVC in contrast-enhanced computed tomography during gastrointestinal bleeding workup. The left-sided IVC formed a hemiazygos-accessory hemiazygos continuation. A narrowing of the right retroaortic renal vein, consistent with the nutcracker phenomenon, was observed. Left-sided IVC, although asymptomatic in the majority of cases, may act as source of diagnostic confusion or contribute to deep vein thrombosis of lower extremities, especially in younger patients. Care must be practiced to establish a comprehensive diagnosis and minimize procedural risks.
