Risk of Multiple Sclerosis Among Persons with Epstein Barr Virus-Positive Mononucleosis: A Population-Based Study.

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 and Objective: Prior studies examining associations between Epstein Barr Virus (EBV)-positive infectious mononucleosis (IM) and risk of multiple sclerosis (MS) frequently lacked laboratory confirmation of EBV-positive IM or relied on billing codes to identify MS. We assessed whether laboratory-confirmed EBV-positive IM was associated with an increased risk of developing verified cases of MS. Methods: We conducted a population-based retrospective cohort study using medical records from the Rochester Epidemiology Project. We identified individuals with serologic evidence of EBV infection and an associated IM diagnosis (EBV-positive IM; exposed cohort) between 1998 and 2022. Age- (± 1 year) and sex-matched individuals without evidence of IM (3:1 match) comprised the unexposed cohort. Incident MS cases were verified through blinded expert chart review. Multivariate Cox proportional hazard models were used to assess associations between EBV-positive IM and risk of MS. Results: 4,721 persons had EBV-positive IM (exposed cohort: 55% female, 70% <20 years). The referent cohort included 14,163 persons without EBV-positive IM (55% female, 70% <20 years). During follow-up (median, 6 years for exposed; 8 years for referents), MS developed in 8 individuals with EBV-positive IM (0.17%) and 10 referents (0.07%). EBV-positive IM was associated with a >3-fold increased risk of MS (adjusted Hazard Ratio: 3.14, 95% Confidence Interval: 1.18-8.34). Discussion: EBV-positive IM was associated with a substantially higher risk of MS. Findings are consistent with prior studies and underscore the importance of preventive strategies targeting EBV to reduce the long-term burden of MS.
