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

Prenatal hydronephrosis is a common finding that resolves spontaneously in low-risk infants. Persistent hydroureteronephrosis requires careful evaluation. This case outlines a rare presentation of ectopic, nonduplicated ureter with distal strictures. A female infant with severe left-sided hydroureteronephrosis was found to have persistent upper tract dilation. Diagnostic cystoscopy with retrograde pyelogram revealed an ectopic, nonduplicated ureter with distal obstruction. Open reconstruction identified a tortuous megaureter with multiple distal strictures, managed with ureteral tapering and reimplantation. Anatomic variants should be considered in infants with persistent hydroureteronephrosis and refractory, recurrent infections. Early recognition and surgical intervention can result in an excellent clinical outcome.
