Brief description

A SAS macro for the Kaplan-Meier plot with SGPLOT Procedure.

This software is released under the MIT License, see http://opensource.org/licenses/mit-license.php.

Software information

  • Author: Kengo NAGASHIMA
  • Version: 1.1.2
  • Last Updated Date: Mar. 23, 2017
  • System Requirements: SAS 9.4 or later, base SAS, SAS/STAT 14.1 or may be later

Version history

  • v1.1.2: fixed a bug: wrong no at risk of the last time point may be produced, if data is sparse
  • v1.1.1: fixed a bug: caused by tie data (thanks to Masashi Mikami)
  • v1.1.0: extended for competing risk
  • v1.0.2: fixed a bug: missing at risk sizes
  • v1.0.1: fixed a bug: caused by censored observations
  • v1.0.0: first release

Example

Kaplan-Meier; confidence interval + risk set (outside)

Kaplan-Meier; confidence interval + risk set (inside)

Kaplan-Meier; risk set (outside)

Kaplan-Meier; risk set (inside)

CIF plot; confidence interval + risk set (outside)

Usage

Arguments

  • data: input dataset name
  • time: time variable
  • event: event variable
  • group: group variable
  • censor_value: code value of censored observations
  • out: output dataset name
  • timemax: maximum time for no. at risk order
  • timeby: increment of the sequence for no. at risk order

If you want to analyze competing risk data

  • event_value: code value of competing risk events

Variables in the output data

  • time: time
  • strata: group
  • est: estimated survival function or cif
  • lcl: lower confidence limit
  • ucl: upper confidence limit
  • left: raw no at risk
  • atrisk: no. at risk table
  • xatrisk: x-axis variable for no. at risk table

If argument 'event_value' is specified

  • adjleft: raw adjusted no at risk
  • adjatrisk: variable of adjusted no at risk table
