Relationships identified survival, causes death withdrawal examined as secondary analyses, where pattern considered exposure.A total 10 306 initiated over period. Of these, 6776 (66%) 1535 (15%) exclusively treated by ICHD PD, respectively, while 136 (1%) ever received HHD during treatment course. remainder both PD: 906 (9%) started on 953 PD. Different seen across patterns. Median survival time 3.0 (95%CI 2.9-3.1) years. Differences groups varied depending period following initiation. an important cause according patterns.This showed that are associated mortality, independent characteristics.
