Inequities in the Use of Disease-Modifying Therapy Among Adults Living With Multiple Sclerosis in Urban and Rural Areas in Alberta, Canada.
Article in Neurology, 2025. 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
objectivesTo compare disease-modifying therapy (DMT) use between people living with multiple sclerosis (pwMS) who resided in rural vs urban areas.
methodsThis retrospective cohort study used population-level individually linked administrative data to identify pwMS on April 1, 2019 (index date), in Alberta, Canada. DMT use was compared between pwMS who resided in rural vs urban areas during a 1-year postindex period. Structural equation modelling (SEM) and logistic regression (with 95% confidence intervals) were applied.
resultsPwMS (n = 4,593) who resided in rural areas (vs urban) were 17% less likely to have received a DMT (odds ratio: 0.83 [0.69-0.99]; SEM total β: -0.032, DISCUSSION: PwMS residing in rural (vs urban) Alberta are less likely to receive any DMT, especially induction/higher-efficacy therapy; this inequality may be mediated by socioeconomic status and geography. Identifying and overcoming barriers to optimal clinical care in this patient population is needed.
