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

Although the clinical progression from lower to upper urinary tract infection is well recognized, the underlying pathophysiology remains understudied. Although vesicoureteral reflux is considered an important factor in pyelonephritis development, the mechanism underlying cases without reflux remains unclear. We report 2 pediatric and adolescent cases in which transient steepening of the ureteral jet angulation and bladder wall thickening were observed on ultrasonography during episodes of cystitis, with subsequent normalization after the resolution of inflammation. These findings suggest that cystitis-induced bladder wall thickening may transiently impair the antireflux mechanism and can provide a possible explanation for some cases of pyelonephritis without documented vesicoureteral reflux.
