Pediatric acute appendicitis: Searching the diagnosis in portal vein.

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.
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
introductionAcute appendicitis is the most common reason for emergency abdominal surgery in the pediatric population. Ultrasound (US) is a widely used modality to diagnose acute appendicitis. The aim of this study was to evaluate the effectiveness of portal vein diameter and flow velocity in acute appendicitis diagnosis.
methodsPortal vein diameter and flow velocity were measured in children who were referred to radiology with a clinical diagnosis of acute appendicitis. The largest appendix diameter and leukocyte count of the patients were recorded. A control group was created which consisted of healthy children, and their portal vein diameter and flow velocities were also measured.
resultsThe median age of the population was 10 years (range, 3-17 years). Mean portal vein diameter was 7.53 ± 1.55 mm in the control group, 7.92 ± 1.88 mm in the other diagnosis group, and 8.76 ± 1.91 mm in the acute appendicitis group. Mean portal vein diameter was significantly higher in the acute appendicitis group (p = 0.001). Median portal vein flow velocity was 17 cm/s (10-29 cm/s) in the control group, 18.3 cm/s (8-27 cm/s) in the other diagnosis group, and 20.5 cm/s in the acute appendicitis group. Median portal vein flow velocity was significantly higher in the acute appendicitis group (p = 0.00).
conclusionDetecting an increase in portal vein diameter and/or flow velocity in equivocal cases may support other clinical signs associated with acute appendicitis. Portal vein diameter and flow velocity can serve as additional diagnostic markers in acute appendicitis cases.
