Evaluation of whether the ultrasonographic onion skin sign is specific for the diagnosis of an appendiceal mucocele.
Article in Journal of medical ultrasonics (2001), 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
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
purposeTo evaluate whether the onion skin sign on ultrasonography (US) of the lower abdomen is specific for the diagnosis of an appendiceal mucocele.
methodsOur study included 231 lesions from 229 patients in whom transabdominal US detected lesions in the lower abdomen and who had definitive pathological diagnoses in the small bowel, ileocecal valve, cecum, appendix, mesentery, adnexa uteri or pelvic cavity outside the major organs. Patients with metastatic tumors were excluded. We reviewed the reports and images from transabdominal US and checked for the presence of the onion skin sign. The sensitivity, specificity, and accuracy of the sign for the diagnosis of an appendiceal mucocele were calculated.
resultsFive (2.2 %) of the 231 lesions showed the onion skin sign on US and all were diagnosed with an appendiceal mucocele. The sensitivity, specificity, and accuracy of the sign for the diagnosis of an appendiceal mucocele were 63, 100, and 99 %, respectively.
conclusionsThe onion skin sign in the lower abdomen appears to be specific for the diagnosis of an appendiceal mucocele. In cases where the onion skin sign is obviously present in the lower abdomen on US, an appendiceal mucocele should be considered as the leading diagnosis.
