The Value of Oligoclonal Bands in Multiple Sclerosis Compared to Other Neurological Disorders: A Retrospective Data Analysis From an Austrian Tertiary Center.
Article in European journal of neurology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundCerebrospinal fluid (CSF) analysis is key to diagnosing multiple sclerosis (MS). In particular, the presence of CSF-specific oligoclonal bands (OCB) is examined alongside differential diagnostic aspects. This study aims to investigate the diagnostic value of OCB in MS compared to other neurological disorders.
methodsPatients who presented to the Department of Neurology of the Medical University of Vienna between January 1, 2004 and December 31, 2020, due to neurological complaints and underwent lumbar puncture (LP) for diagnostic purposes were included in this retrospective analysis. Exclusion criteria were incomplete laboratory data and/or a missing final diagnosis.
resultsOf 5744 patients who underwent LP, 5225 were available for analysis. Of these, 745 (14.3%) were diagnosed with MS, whereby CSF-specific OCB showed a sensitivity of 92.8% and a specificity of 90.4%. While the positive predictive value (PPV) was merely 61.5%, the negative predictive value (NPV) yielded 98.7%. In comparison, OCB displayed low sensitivity rates for most other neurological disease groups. Of note, neuroborreliosis (n = 66) had a relatively high OCB positive rate of 70%, followed by CNS human immunodeficiency virus infections (n = 32) with 62.5%.
conclusionsCSF-specific OCB have a high sensitivity and specificity and a very high NPV for diagnosing MS. However, the PPV was lower in this cohort. These findings must be carefully considered when diagnosing MS and interpreting OCB, especially in the context of differential diagnostic workup.
