Use PROC LIFETEST to generate Kaplan-Meier product-limit survival estimates, and understand the output of the LIFETEST procedure. Generate confidence limits for the Kaplan-Meier curve. Understand upgrades in SAS 9 for obtaining confidence bands for the KM survivor function. Use the LIFETEST procedure to compare survival times of two or more groups.

OS, including 5-year survival rate or probability of recurrence by the end of the study (August, 2018), was analysed using Kaplan-Meier and univariate and multivariate Cox regression modeling. All data were analyzed using Statistical Analytic System software (v. 9.1, 2005; SAS Institute, Cary, NC, USA).

Percentage of fish positive for S. iniae and mortality of fish from different treatments were analyzed with Duncan multiple range tests (SAS Institute 1989). Median days to death were calculated and compared by Lifetest procedure (SAS Institute 1989) (Kaplan-Meier method). Probabilities less than 0.05 were considered significant. RESULTS

It’s not straightforward to make this plot. Luckily, we can just call for a Kaplan-Meier Curve, which gives the empirical survival curve adjusted for censoring: Non-Parametric Regression in SAS: PROC LIFETEST . Plot the Kaplan-Meier survival curve for the hmohiv data. /**Kaplan-Meier estimate of survivorship function**/ /*Plot KM curve*/

A sensitive analysis, based on the Kaplan Meier method was performed and results are presented in the Supplementary Appendix. Univariate and multivariate effect of baseline features on risk of AF occurrence and transition to higher AF burden thresholds were estimated by Cox proportional hazard models.

Comparisons of baseline data were performed using the chi-square test or Fisher’s exact test (categorical variables) and Student’s t-test (continuous variables) as appropriate. We estimated the cumulative event rate using the Kaplan-Meier method and calculated the …
