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

purposeShunt thrombosis is an important complication after proximal splenorenal shunt (PSRS) in children with extrahepatic portal vein thrombosis (EHPVT). We evaluated whether preoperative vascular parameters are associated with postoperative PSRS patency.

methodsOf 139 non-cirrhotic patients who underwent PSRS for EHPVT, 86 with adequate preoperative imaging and follow-up were included in this retrospective single-center study. The aortomesenteric angle, splenic and left renal vein diameter were measured on preoperative CT, and spontaneous splenorenal shunt presence was recorded. Shunt patency was assessed from postoperative imaging. Correlation, Firth penalized logistic regression, and ROC analyses were performed.

resultsMean age was 114 ± 50 months; mean follow-up 81 ± 51 months. Patency was preserved in 69 patients (80.2%) and 17 (19.8%) developed thrombosis. No parameter was associated with patency: aortomesenteric angle (r = 0.035), splenic vein diameter (r = 0.039), left renal vein diameter (r = 0.111), or spontaneous splenorenal shunt (r = 0.005) (all p > 0.05). Firth regression identified no independent predictors, and the aortomesenteric angle showed non-significant discrimination (AUC = 0.64, 95% CI 0.485-0.795, p = 0.076).

conclusionPreoperative vascular parameters were not associated with postoperative PSRS patency in pediatric EHPVT. Static anatomical measurements have limited predictive value for shunt outcomes.
