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

aim of the studyTo present a case series of four pediatric patients with PDPV, each with a different clinical presentation and surgical management.

methodsWe retrospectively reviewed four cases of PDPV managed at our institution. Two cases were associated with extrahepatic biliary atresia (EHBA) and discovered incidentally during surgery. The other two cases presented with duodenal obstruction but had differing etiologies and management approaches.

resultsTwo patients with EHBA underwent successful Kasai portoenterostomy; PDPV was discovered intraoperatively and required no intervention. One patient had duodenal obstruction due to PDPV compressing the duodenum and underwent laparoscopic duodenoduodenostomy. Another patient had duodenal obstruction due to malrotation; a Ladd's procedure was performed. PDPV was noted intraoperatively but was not the obstructing factor.

conclusionPDPV can present variably, ranging from an incidental finding to a causative factor in duodenal obstruction. Its recognition is crucial during abdominal surgery to avoid inadvertent injury and to tailor the surgical approach based on associated anomalies.
