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

objectivesTo evaluate dynamic contrast-enhanced ultrasound (DCEUS) potential for diagnosing ureteropelvic junction obstruction (UPJO). We hypothesize that DCEUS can identify differences in renal parenchymal microcirculation between normal and obstructed kidneys. MATERIALS AND

methodsThis prospective study included 8 subjects (16 kidneys) with unilateral renal obstruction clinically determined to need surgery and confirmed by nuclear medicine (NM) diuretic half-time (

resultsMTT was significantly longer in obstructed kidneys compared to normal kidneys before surgery (

conclusionDCEUS MTT shows promise as a diagnostic tool for assessing UPJO, potentially serving as a stand-alone or complementary modality to NM without additional ionizing radiation. Further trials with larger cohorts and those with non-obstructing hydronephrosis are required to confirm its clinical utility.
