Susceptibility-weighted imaging and transcranial Doppler ultrasound in patients with cerebral small vessel disease.
Article in Neurological sciences : official journal of the Italian Neurological Society and of the Italian Society of Clinical Neurophysiology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
introductionCerebral small vessel disease (SVD) is a common accompaniment to aging. Magnetic resonance imaging (MRI) features of SVD include lacunar infarcts (LI) and white matter hyperintensity (WMH). Brain iron deposition is also a known marker of SVD that is associated with cognitive impairment and can be detected with susceptibility-weighted imaging (SWI) MRI technique. According to recent studies, the pulsation of cerebral blood flow can be one of the main factors of the development of pathological brain changes in elderly patients. The objective of this study was to investigate the relationship between the brain iron deposition, cerebral blood flow pulsation, and cognitive impairment in patients with SVD. MATERIALS AND
methodsFor the study, 97 patients with diagnosed SVD were selected. The patients were divided into two groups based on the Montreal Cognitive Assessment (MoCA) test scores. All patients underwent MRI in the SWI sequence. Pulsatility index (PI) and resistivity index (RI) were recorded from the middle cerebral artery bilaterally using transcranial Doppler (TCD).
resultsThe linear regression model showed that the pulsatility index (PI) and resistivity index (RI) were associated with cognitive impairment and brain iron deposition in basal ganglia. The most significant association was found between left globus pallidus severe hypointensity voxels count and left middle cerebral artery (MCA) RI (p = 0.009).
conclusionThe results of the study provide information that TCD indicators may be associated with brain iron deposition and cognitive decline in patients with SVD. Our findings suggest that both brain iron deposition and cerebral hemodynamics abnormalities may play an important role in the pathophysiological mechanisms of SVD.
