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
Background: Pulsatile tinnitus (PT) is a common symptom in idiopathic intracranial hypertension (IIH). Previously published work suggests that the severity of individual MRI findings associated with IIH does not correlate with the presence of PT. However, recent studies suggest that other symptoms of IIH may be related to the number (rather than severity) of abnormal MRI findings. The purpose of this study is to determine if there is a difference in the number of abnormal MRI findings in those with and without PT. Methods: We performed a retrospective, age-matched cohort study of patients with documented IIH and MRI head, assessing for the total number of abnormal MRI findings out of 16 variables associated with IIH. The groups were then stratified in numerous ways. Analysis was performed on each of these grouping strategies to assess the difference between PT+ and PT- cohorts and between low-, medium-, and high-number abnormal findings groups. Results: A total of 80 age-matched patients met the inclusion criteria (40 PT+, 40 PT-). There was no statistically significant difference in the number of positive MRI findings between PT+ and PT- cohorts, 6.13 ± 2.77 and 6.68 ± 3.47, respectively ( Conclusions: The presence of PT does not correlate with the total number of MRI abnormalities. This reinforced current evidence that PT in patients with IIH is likely not related to the severity or chronicity of IIH.
