Figure 4. Urinary extracellular domain of p75 (p75^ECD) at baseline predicts future survival.

Kaplan-Meier survival estimates comparing 27 patients with amyotrophic lateral sclerosis who had baseline urinary p75^ECD above (red dashed line) and 27 with values below (black line) the median (5.3 ng/mg creatinine), illustrates the longer median survival in those with lower compared to higher urinary p75^ECD levels (13.9 vs 8.9 months; Wilcoxon test p = 0.024).
