In contrast, 87% of IGF‐1‐deficient mice developed signs of hypertension‐induced intracerebral hemorrhage (Fig. 1C), which occurred within a similar time window (the maximum difference between the cumulative distribution curves for time‐to‐event in the two groups, D, is as follows: 0.2063; P = 0.753). This evidence concerns the gene IGF1 and intracerebral hemorrhage.
