Figure 3:

Pairwise hazard ratios for exon skippable subgroups based on Model I. Muscular Dystrophy Surveillance, Tracking, and Research Network (MD STARnet) 1982–2012. Pairwise hazard ratio (HR) estimates for each exon skippable subgroup when controlling for steroid use. A HR estimate greater than one indicates a younger age for loss of ambulation for the group on the left hand side relative to the group listed on the right hand side. Right facing arrows indicate an estimated HR larger than 10. Confidence intervals are corrected for multiple comparisons using the Tukey-Kramer method.
