Prophylactic Use of Cardiac Medications and Survival in Duchenne Muscular Dystrophy.
Article in Muscle & nerve, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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/
aimsProphylactic treatment of left ventricular dysfunction (LVD) in Duchenne muscular dystrophy (DMD) delays onset of LVD, but there is limited data showing impact on survival. Our aim was to describe survival among treated and untreated individuals with DMD.
methodsRetrospective, population-based surveillance data from the Muscular Dystrophy Surveillance, Tracking and Research Network (MD STARnet) were used. We analyzed 327 males with DMD born between 1982 and 2009 who were at least 6 years old at the last visit and who initiated cardiac prophylactic medication before age 14 years. Death status was ascertained through vital record linkages and medical record review. Prophylaxis was defined as cardiac medication use at least 1 year before LVD onset (ejection fraction < 55% or shortening fraction < 28%). Age at first visit, corticosteroid use, scoliosis surgery, initiation of noninvasive ventilation, and loss of ambulation were also coded. Cox Proportional Hazard modeling with time-varying covariates describes associations.
resultsProphylactic cardiac treatment was documented for 27.7% (n = 90); corticosteroids were used by 60.9% (n = 157). Adjusting for age at first visit and MD STARnet site, prophylactic treatment was associated with a 54% lower hazard of death (HR = 0.46, 95% CI = 0.22-0.93) compared to no prophylaxis. Adjusting for selected clinical covariates did not appreciably change the estimate (HR = 0.46, 95% CI = 0.22-0.99). DISCUSSION: Initiation of cardiac medication when left ventricular function is normal was associated with prolonged survival in this study of males with DMD. Only one-quarter of individuals received this treatment, however, indicating a topic of focus for improving care.
