From: Better survival in female SOD1-mutant patients with ALS: a study of SOD1-related natural history
Age at onset (AAO) of patients with SOD1 mutations. a Plot of rank ordered SOD1-mutant patients showing the median AAO of 43 years. b Plot comparing the AAO among patients carrying mutations in different exons of the SOD1 gene. Patients (n = 24) harbouring mutations in exon 2 were older than those (n = 18) harbouring mutations in exon 4 (46.63 years vs 37.75, p = 0.002). c Plots comparing fALS patients with sALS patients and (d) plots comparing male patients with female patients; neither comparison identified a significant difference in AAO (p = 0.64 and 0.53, respectively)
