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

purposeThis study aimed to identify predictors of portal vein thrombosis (PVT) after laparoscopic splenectomy (LS) in children.

methodsPatients who underwent LS between September 2014 and August 2024 were retrospectively reviewed. Preoperative and intraoperative clinical data were compared between those with and without PVT. The splenic vein diameter (SVD) was measured at 2, 4, and 6 cm from the portal vein (PV) junction using preoperative transaxial computed tomography images.

resultsAmong 21 patients who underwent LS, those with PVT were significantly older, more likely to be female, and had a higher body mass index. Although splenic maximum diameter, PV diameter, and the spleen volume/standard spleen volume ratio showed no significant differences, SVD was significantly larger at all measured locations in patients with PVT. Additionally, the SVD/portal vein diameter (PVD) ratio was significantly higher at all measured locations in these patients. Receiver operating characteristic analysis identified the SVD/PVD ratio as the most reliable predictor of PVT development, with an optimal cutoff value of 0.7.

conclusionAn SVD/PVD ratio ≥ 0.7 is a strong predictor of PVT after LS in children. Measuring this ratio preoperatively may identify high-risk patients, allowing for closer monitoring and potential preventive interventions to reduce PVT incidence.
