Figure 2. Kaplan-Meier survival curves.

Figure 2

For all ALS patients (A), survival was significantly longer (p<0.014) in patients with high cystatin C levels (n = 21) than in patients with low cystatin C levels (n = 11). For patients with limb onset ALS (B), the same trend was observed, but with a larger survival difference (p<0.010) between patients with high (n = 13) and low (n = 10) cystatin C levels.
