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: Cerebral small vessel disease (CSVD) is a major contributor to stroke, cognitive impairment, and gait disturbance. Data describing its burden and determinants in Middle Eastern populations remain limited. This study aimed to estimate the prevalence, clinical predictors, and neuroimaging characteristics of CSVD among adults undergoing brain MRI in Saudi Arabia and to examine associations with vascular risk factors and antihypertensive therapy. Methods: We conducted a retrospective cross-sectional study of adults aged 40-70 years who underwent brain MRI at King Abdulaziz Medical City, Riyadh, between January 2018 and January 2019. CSVD markers were identified according to the STandards for ReportIng Vascular changes on nEuroimaging (STRIVE) criteria, and white matter hyperintensities were graded using the Fazekas scale. Multivariable logistic regression models were constructed to identify factors independently associated with CSVD. Results: Among 644 participants undergoing brain MRI, CSVD was identified in 36.5% of patients. Prevalence increased markedly with age, rising from 18.2% in individuals aged 40-50 years to 54.1% in those aged 60-70 years (p < 0.001). In the multivariable etiological model, hypertension emerged as the strongest independent vascular predictor of CSVD. White matter hyperintensities were the most frequent imaging manifestation and increased in severity with advancing age. Among hypertensive patients, certain antihypertensive classes, particularly calcium channel blockers and ACE inhibitor/ARB monotherapy, were associated with lower odds of CSVD compared with untreated hypertension. Conclusion: In this MRI-based clinical cohort from Saudi Arabia, CSVD was present in more than one-third of adults aged 40-70 years undergoing neuroimaging. Disease prevalence increased substantially with advancing age and vascular comorbidities. These findings highlight the importance of vascular risk factor control and provide important regional data on the clinical and imaging profile of CSVD in Middle Eastern populations.
