Evaluation and analysis of the transmission route of sigmoid sinus tinnitus by HRCT of the temporal bone: A retrospective analysis.
Article in Science progress. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveThis study aims to analyze anatomical parameters of the transmission route of sigmoid sinus tinnitus (SST) to explore its mechanism and speculate on possible responsible anatomical abnormalities.
methodsClinical data were retrospectively collected from SST and sigmoid sinus wall dehiscence (SSWD) patients suggested by temporal bone high resolution computed tomography (HRCT), with and without tinnitus, at the First Affiliated Hospital of Chongqing Medical University from January 2015 to August 2022. Patients were divided into SSWD tinnitus (
resultsThe tinnitus group was significantly younger and had more severe low-frequency hearing loss (
conclusionsSST patients exhibit significant female and right-sided predominance, with low-frequency hearing loss. Defects in the superior curvature and descending part of the sigmoid groove are more likely to cause tinnitus. Larger transverse diameters and higher S/V values are independent risk factors for tinnitus. Over-pneumatized temporal bones do not facilitate transmission of sigmoid sinus blood flow murmur, highlighting the importance of specific anatomical features in SST development.
