1 · What the graph read from it

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.

2 · The registry

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

backgroundThe clinical characteristics of multiple sclerosis (MS) in individuals aged 65 years and older remain scarcely studied. This retrospective study compared late-onset MS (LOMS, onset ≥ 50 years) and adult-onset MS (AOMS, onset 18-49 years) in older adults with MS (OAwMS) aged ≥ 65 years.

methodsData of subjects aged ≥ 65 years with a confirmed MS diagnosis and a recorded age at onset were collected from the Finnish MS registry at Tampere University Hospital, excluding individuals with paediatric-onset MS. Demographics, disease-modifying therapy (DMT) use, relapse history and Expanded Disability Status Scale (EDSS) scores were compared between LOMS and AOMS groups.

resultsThe cohort included 248 subjects (41 LOMS, 207 AOMS). Primary progressive MS (PPMS) was more common in LOMS when compared to AOMS (41.5% vs. 12.6% at data acquisition, p < 0.001). Among subjects with a history of relapsing-remitting MS (RRMS) (32 LOMS, 178 AOMS), DMT had been used by 25.0% and 27.5% of subjects with LOMS and AOMS, and relapses after age 65 occurred in 18.8% and 7.3% of subjects with LOMS and AOMS, respectively. Subjects with LOMS discontinued DMT at an older age when compared to those with AOMS (mean 64.0 vs. 58.8 years, p = 0.04). No age-related differences in EDSS were observed after age 65.

conclusionsPPMS was more common among subjects with LOMS. Among subjects with a current or previous diagnosis of RRMS, occasional relapses were observed after age 65 in both groups, though multiple relapses were rare. These findings support the need for individualised care of OAwMS.
