Characterizing Perinatal Treatment Patterns and Outcomes in Myasthenia Gravis.
Article in Muscle & nerve, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
INTRODUCTION/
aimsStudies on pregnancy in myasthenia gravis (MG) are limited by small sample sizes or examine a limited number of outcomes. The objective of this study was to estimate the prevalence of perinatal and infant outcomes and characterize perinatal treatment patterns in MG.
methodsWe conducted a retrospective cohort study in Merative MarketScan Commercial Claims and Encounters (CCAE) and two other United States health insurance claims databases. Pregnancies in females aged 18-49 years were identified and maternal and infant records were linked. MG was defined by ≥ 1 inpatient or ≥ 2 outpatient diagnoses within a 365-day period. The prevalence of six perinatal outcomes was calculated in the MG and total populations. Treatments were summarized by class.
resultsIn pregnancies from CCAE between 2000-2023, preeclampsia (10.7% vs. 7.1%), Cesarean section (42.9% vs. 36.7%), preterm birth (18.0% vs. 9.9%), and small for gestational age (4.3% vs. 1.7%) were more frequent among MG (n = 900) than the age-adjusted total population (n = 5,185,726). Lack of treatment for MG was common across the perinatal period: 54.3% were untreated in the 6 months preconception, 61.2% in pregnancy, and 57.8% in the 6 months postpartum. Of those taking acetylcholinesterase inhibitors or corticosteroids in pregnancy, 21.8% and 33.1% had not been taking them before pregnancy, respectively. DISCUSSION: MG was associated with a greater prevalence of certain perinatal outcomes, occurring in both mother and infant. In parallel, though most patients did not receive treatment in pregnancy those who did showed variation over time, suggesting a potential need for this population.
