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

A 49-year-old woman presented with right flank pain and hematuria. Computed tomography demonstrated a nonfunctioning pelvic ectopic kidney with severe hydronephrosis and cortical thinning. Nephrectomy revealed an abnormally attached, markedly dilated ureter coursing anteriorly along the renal surface and abruptly narrowing distally. Histological examination of the transition zone demonstrated two distinct urothelial-lined lumina within a shared lamina propria and common muscularis propria and adventitia, with distal reconstitution into a single lumen. The findings support a rare focal double-lumen ureter associated with an ectopic kidney and chronic obstructive nephropathy.
