Sex- and age-related shift of relapse phenotypes in a cohort of relapsing multiple sclerosis patients: Post hoc analysis from the OPERA phase 3 trials.
Trial report in European journal of neurology, 2024. 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
background and purposeRelapse presentation in relapsing multiple sclerosis (RMS) differs between sexes, leading to differential outcomes. An influence of age seems likely but is less well investigated separately for women and men.
methodsUsing the large well-defined dataset of the pivotal trials of ocrelizumab in RMS, OPERA I and II, and their open-label extension, we performed a post hoc analysis to investigate relapse phenotypes for sex- and age-related differences in n = 929 relapses in 534 subjects (171 men, 363 women). Frequencies of affected functional systems were analyzed separated by sex and for three age strata (<35, 35-44, ≥45 years). Exact p-values are given for this exploratory analysis.
resultsFrequencies of mono- versus polysymptomatic relapse presentations were different neither between sexes nor in different age groups. Cerebellar symptoms were more frequent in relapses in men (female [f]: 23.1%, male [m]: 33.0%, p = 0.002), and women's relapses included more sensory (f: 53.8%, m: 32.3%, p < 0.001) and fatigue symptoms (f: 22.6%, m: 14.7%, p = 0.006). Whereas the sex difference for sensory involvement was present over all age groups (<35 years: f: 58.3%, m: 30.4%, p < 0.001; 35-44 years: f: 53.7%, m: 36.0%, p = 0.003; ≥45 years: f: 47.8%, m: 28.8%, p = 0.009), the difference for cerebellar involvement diminished with age (<35 years: f: 20.1%, m: 33.3%, p = 0.009; 35-44 years: f: 22.7%, m: 34.2%, p = 0.034; ≥45 years: f: 27.8%, m: 30.3%, p = 0.750). Relapse presentation seemed to shift with age in women only.
conclusionsWe describe sex-specific relapse presentations and an influence of age only for women. Underlying causal factors warrant further investigations.
