Inter- and Intrarater Reliability of the Manjila and Semaan Classification System when Assessing Jugular Bulb Position.

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
Objectives: This study evaluates the inter- and intrarater reliability of the Manjila and Semaan classification system for the anatomical position of the jugular bulb. The classification system, proposed in 2018, aims to address inconsistencies in reporting that impact communication between radiologists and skull base surgeons and affect surgical planning. Design: Bilateral jugular bulb positions on 50 consecutive computed tomography (CT) venography examinations were assessed by two neuroradiology attending physicians, two neuroradiology fellows, and two radiology residents. Setting: The study was conducted in a clinical radiology setting on an Ambra PACS workstation. Participants: Consecutive patients who underwent clinical CT venography examinations between August 3, 2021, and January 29, 2022, and met the inclusion criteria were included in the analysis. Main Outcome Measures: Inter- and intrarater reliability were assessed using kappa values, Kendall's coefficient of concordance ( Results: Interrater agreement, measured by kappa values, showed moderate to substantial agreement for bilateral jugular bulb position types. Kendall's Conclusion: The Manjila and Semaan classification system demonstrated high inter- and intrarater reliability across a spectrum of experience levels. Adopting this classification could enhance clinical communication and improve surgical planning.
