Reliability of fast-spin echo T2-weighted three-dimensional sequences to predict endoscopic third ventriculocisternostomy patency in children.

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
purposeClinical and radiological assessment of endoscopic third ventriculocisternostomy (ETV) patency can be challenging in children. The objective of our study was thus to test the accuracy and interrater reliability of 3D fast-spin echo (FSE) T2-weighted sequences to assess the patency of ETV.
methodsWe included all the consecutive children who underwent surgery for ETV over a two-year period and selected the children who presented ETV dysfunction and matched them with children without dysfunction. We evaluated the Kappa interrater reliability of three experienced physicians for prediction of ETV patency using solely the flow void sign in 3D FSE T2-weighted sequences.
resultsNineteen children underwent surgery for ETV dysfunction and 12 children without dysfunction were matched. Sensitivity was 0.79, 0.89 and 0.84 and specificity was 1 for all raters. None of the patent ETV was wrongly considered to be dysfunctional. Fleiss' kappa was 0.871 (p < 0.001). The interrater reliability was excellent with respect to the patency or not of the ETV.
conclusionFSE T2-weighted sequence is a simple and reproducible tool that can be widely used in daily practice to assess the patency of ETV. Interrater reliability of this sequence is high and accessibility in outpatient setting is acceptable.
