Evaluation of cognitive impairments in multiple sclerosis: a comparative analysis of the Rey complex figure test and the symbol digit modalities test.
Article in Arquivos de neuro-psiquiatria, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Cognitive impairment is common in multiple sclerosis (MS), and visual memory impairments are increasingly considered clinically important, yet still underappreciated.To compare cognitive performance assessed by the Rey Complex Figure Test (RCFT) and Symbol Digit Modalities Test (SDMT) in MS patients and healthy controls, and to examine correlations between these measures and physical disability indices.A total of 177 participants were assessed using RCFT subtests and SDMT, of whom 95 had relapsing-remitting MS (RRMS) and 82 were healthy controls. Group comparisons and correlation analyses were performed.The MS patients scored significantly lower on all RCFT subtests and SDMT. Moderate correlations were found between SDMT and RCFT 0 to 2, but not RCFT 3.Both RCFT and SDMT may serve as potentially complementary measures of cognitive domains relevant to MS. Incorporating both recall and recognition-based measures, along with processing speed assessments, can provide a broader evaluation of cognitive strengths and weaknesses in MS, helping clinicians better characterize patients' profiles.
