Microsoft Excel Program for creating attractive survival curves

Abstract

This paper describes the design of a Microsoft Excel Program which interactively creates attractive and outstanding survival curves. This program enables medical researchers to easily create quality presentation graphs of survival curves and obtain high quality slides and prints, which can be inserted in papers or used directly at medical meetings. Through the use of vertical bars, this program can display the exact points where censored cases occur on survival curves, making it possible to monitor censoring patterns between groups. Furthermore, this program can also create survival curves based on the proportional hazards model for specific patterns of covariate values, given estimated regression coefficients and baseline survival function. This program may be a most useful and effective tool in creating medical research papers containing survival analysis.
