Fig. 2

The cumulative risk of NV in DMD patients stratified by ADRB2 genotype. The cumulative risk function was obtained from Cox regression modeling of the risk of nocturnal ventilation where genotype group, patient age at entry into the study, ambulatory status, corticosteroid-use, weight, and FVC were entered into the model as covariates. The risk curves was produced for each genotype variant by holding all other covariates in the Cox model constant at their respective means (Age = 12.2 yrs.; Mass = 43.1 kg; Corticosteroid-use = 3.4 yrs.; Ambulatory status = 0.60; FVC = 1.71)
