a-e. Kaplan-Meier curves of the endurance shuttle tests. Probability of drop-out since test initiation on the Endurance Shuttle Nine Hole Peg Test (ESNHPT) (a-b), Endurance Shuttle Box and Block Test (ESBBT) (c-d), Endurance Shuttle Walk Test (ESWT) (e) and a composite figure of all separate Endurance Shuttle Tests and the Endurance Shuttle Test Combined Score (ESTCS) (f). SMA: all patients with SMA; HC: Healthy Controls and DC: Disease Controls. SMA sub groups: SMA type 2, SMA type 3a and SMA type 3b and 4. Subjects that completed the Endurance Shuttle Tests are censored. The intersection of the horizontal and vertical dashed lines depict the median time to drop-out.
