Figure 2. Fat Fraction and Transverse Relaxation Time (qT₂) Across Multiple Muscles Based on Quantitative Magnetic Resonance Imaging (MRI) and Spectrometry (MRS).

The fat fraction (A) and qT₂ (B) were lower in participants in the SRP-9001 cohort across multiple leg muscles compared with those in the natural history cohort. Due to motion artifact, no upper leg qT₂ data were available for 1 participant in the SRP-9001 cohort. Although statistical analysis was not performed, group mean data reflected lower quantitative MR biomarker values in the SRP-9001 cohort. Dots indicate individual data points; center lines, means; whiskers, SDs.
