This table shows the crude survival probabilities and crude and adjusted HRs with corresponding 95% confidence intervals comparing the survival of the time periods 2008–10 and 2011–13 with the time period 2008–10 used as a reference. Bold numbers indicate whether the HRs were statistically significantly (P < .05) different from the reference. A HR below 1 indicates improvement in survival over time (i.e. the more recent time period 2011–13 had better survival compared with the period 2008–10).
HR, hazard ratio; KRT, kidney replacement therapy.
