Survival curve as Figure 2 with 95% confidence interval lines on either side of the curve, very close at time 0 and getting further apart until at about time 200 they are about 0.05 above and below the survival curve, which they roughly parallel in a rather irregular way until time 1100, getting slightly further apart towards the end.
