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

backgroundPregnancy has been observed to reduce the frequency of relapses in Multiple Sclerosis (MS) patients, but the relapse risk tends to increase during the early post-partum period. Increased pre- and post-partum disease activity may predict a poor long-term prognosis. This study aimed to evaluate the correlation between magnetic resonance imaging (MRI) activity during the year before pregnancy and long-term clinically meaningful worsening in Expanded Disability Status Scale (EDSS).

methodsThis observational, retrospective, case-control study included 141 pregnancies in 99 females with MS. Statistical analyses were used to evaluate the correlation between MRI activity during the year pre-pregnancy and post-partum clinical worsening during a 5-year follow-up. Clustered logistic regression was used to investigate the predictors of 5-year clinically meaningful worsening in EDSS (lt-EDSS).

resultsWe found a significant correlation between an active MRI pre-pregnancy and lt-EDSS (p = 0.0006). EDSS pre-pregnancy and lt-EDSS were also significantly correlated (p = 0.043). Using a multivariate model, we predicted which females would not experience long-term clinical deterioration by a stable MRI pre-pregnancy (92.7% specificity; p = 0.004).

conclusionsAn active MRI pre-conception is a strong predictor of lt-EDSS and a higher annual relapse rate during the follow-up period, regardless of whether the female had clinical evidence of disease activity prior to conception and delivery. Optimizing disease control and achieving imaging stability prior to conception may reduce the risk of long-term clinical deterioration.
