CT and MR imaging findings of infection-free and benign second branchial cleft cysts.

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
purposeThe present study aimed to assess CT and MR imaging findings of infection-free and benign second branchial cleft cysts (SBCCs).
methodsEleven patients with histopathologically confirmed infection-free and benign SBCCs underwent preoperative contrast-enhanced CT (CECT) and/or MR imaging. We assessed qualitative (presence and extent of wall thickening, degree of contrast enhancement of the thickened wall on CECT images, and signal intensity of the thickened wall on T2-weighted images) and quantitative (maximum thickness of the thickened wall) imaging findings.
resultsEccentric and smooth wall thickening was observed in 11/11 (100%) patients. The wall thickening extent (percentage of the thickened wall to the circumference of the wall) was small (1%-25%) in 4/11 (36%), moderate (26%-50%) in 6/11 (54%), extensive (51%-75%) in 1/11 (9%), and diffuse (76%-100%) in 0/11 (0%) patients. Mild homogeneous enhancement of the thickened wall on CECT images was observed in 7/7 (100%) patients. The signal intensity of the thickened wall on T2-weighted images was isointense relative to that of normal lymph nodes in 7/8 (88%) and mildly hyperintense in 1/8 (12%) patient. The maximum thickness of the thickened walls ranged from 2 to 4 (mean 3.4) mm.
conclusionsInfection-free and benign SBCCs are identifiable as cysts with eccentric and smooth wall thickening on CECT and MR images. The wall thickness was almost always less than half of the wall circumference, isointense relative to normal lymph nodes, and showed mild homogeneous enhancement.
