A comparative study of cognitive impairment in sporadic and familial cases of multiple sclerosis.

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
Genetics plays a significant role in Multiple Sclerosis (MS), with approximately 12.6% of cases occurring in familial form. While previous studies have demonstrated differences in disease progression and MRI findings between familial and sporadic MS, there has been no comparison of cognitive impairment between them. In this study, we evaluated cognitive performance among patients with sporadic and familial MS, along with a healthy control group. A total of 130 individuals, matched for age, sex, and education, were recruited for each group. The mean age of participants was 37.8 ± 9.8 years, and 77.6% of them were female. Cognitive performance was assessed using the Brief International Cognitive Assessment for MS (BICAMS) across the three groups. Both familial and sporadic MS patients showed poorer cognitive performance in the Symbol Digit Modalities Test (SDMT) (Familial: 46.96 ± 12.59, Sporadic: 45.88 ± 14.13, Normal: 56.48 ± 11.89), California Verbal Learning Test (CVLT) (Familial: 66.90 ± 14.01, Sporadic: 68.19 ± 16.49, Normal: 75.18 ± 13.02), and the Brief Visuospatial Memory Test-Revised (BVMT-R) (Familial: 24 (12), Sporadic: 24 (12), Normal: 35 (4)) compared to healthy controls. Meanwhile, no significant differences in cognitive impairment were observed between the familial and sporadic MS groups in the SDMT (p = 1.000), CVLT (p = 0.775), and BVMT-R (p = 0.733). Furthermore, this study found significant relationships between education, depression, age, and sex with different aspects of cognitive performance in MS. Overall, both familial and sporadic MS patients demonstrated similar levels of cognitive impairment.
