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

Background: This report describes the first documented case of renal agenesis associated with ectopia of the contralateral kidney in a feline in veterinary medicine. Unilateral renal agenesis is a rare congenital anomaly characterized by the complete absence of one kidney. Renal ectopia, in turn, refers to the anomalous location of the kidney and is a rare condition. The simultaneous occurrence of these anomalies is extremely uncommon. Case Description: A 2-year-old spayed female mixed-breed cat presented with apathy, hyporexia, and vomiting. Laboratory tests revealed azotemia, and imaging tests confirmed the absence of the right kidney and the ectopic position of the left kidney, as well as alterations compatible with chronic kidney disease. Abdominal ultrasonography and excretory urography confirmed the diagnosis. Conclusion: Coexisting renal agenesis and ectopia are rare conditions in humans, and there are no reports of them in felines. Despite its rarity, the condition is compatible with life, as long as it is diagnosed early and continuously monitored.
