Added value of graded compression ultrasound to the Alvarado score in cases of right iliac fossa pain.

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 one of the most common emergencies treated by the general surgeon. Simple appendicitis can progress to perforation, which is associated with a much higher morbidity and mortality, and surgeons have therefore been inclined to operate when the diagnosis is probable rather than wait until it is certain. The aim of this study was to evaluate the sensitivity and specificity of the Alvarado score combined with ultrasounds of the abdomen and pelvis in cases of right iliac fossa pain with suspected acute appendicitis.
methods100 patients admitted to the Department of Surgery at Alexandria Main University Hospital in 2013 complaining of right iliac fossa pain with suspected acute appendicitis were studied prospectively. The demographic information, histopathology, physical examination, laboratory data, Alvarado score, sonography report and histopathological reports of these patients were gathered. The treating surgeon made decisions for surgery or conservative management without any intervention from the research team.
resultsA combination of methods showed that Alvarado alone was 100% sensitive in excluding appendicitis at scores below five and was highly specific at scores above eight (91.9%) with no added value when combining it with ultrasound in those scores. On the other hand, ultrasound was beneficial only in patients with Alvarado scores between five and eight for detecting appendicitis and not excluding it (increasing specificity to 100% and not affecting sensitivity).
conclusionUltrasound is a good adjuvant examination in cases with Alvarado scores between five and eight in order to diagnose appendicitis. Negative ultrasound results do not exclude appendicitis and further assessment by other modalities should be performed.
