Figure 1. Cumulative incidence of permanent hemodialysis access recreation and the composite endpoint for statin users and non-users by the multivariate Nelson-Aalen method.

Statin users had significantly lower incidence rates of permanent hemodialysis access recreation than statin user group in (a) overall pairs and (b) arteriovneous fistula pairs, but not in (c) arteriovenous graft pairs. Incidence rates of composite endpoint, permanent hemodialysis access recreation or angioplasty, for statin users were significantly lower than nonusers in (d) overall pairs (e) and arteriovneous fistula pairs (f), but not in arteriovenous graft pairs.
