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

While horseshoe kidneys are the most common renal fusion anomaly, various complex variant anatomies exist. One rare form is the retroaortic retrocaval reverse horseshoe kidney, where the upper poles fuse posterior to both the aorta and inferior vena cava. These intricate renal anomalies increase complication risk and complicate surgical interventions. We report a 3-year-old boy diagnosed with a retroaortic retrocaval reverse horseshoe kidney during a spinal deformity evaluation. This case is one of few instances of this specific variant documented in the literature and is the first to be associated with type 1 diastematomyelia and tethered cord.
