Area of Science:

  • Biostatistics
  • Medical Informatics

Background:

  • Access to advanced statistical analysis for patient survival data is often limited to mainframe users.
  • Microcomputers offer a potential platform for sophisticated medical research tools.

Purpose of the Study:

  • To develop a user-friendly microcomputer program for calculating patient survival probabilities.
  • To enable tabulation of survival data into life tables.
  • To facilitate comparison of two patient groups using the Mantel-Haenszel (logrank) test.

Main Methods:

  • The program accepts data in text or dBASE III/III plus formats.
  • It features a menu-driven interface for ease of use.
  • Survival probability calculations and Mantel-Haenszel logrank tests are performed.

Main Results:

  • A functional program was created for microcomputer-based survival analysis.
  • The program successfully tabulates results in life tables.
  • It allows for comparative analysis between patient cohorts.

Conclusions:

  • This microcomputer program democratizes survival analysis, making it accessible to a wider research community.
  • It provides a valuable tool for researchers lacking mainframe resources.
  • The software enhances the feasibility of conducting survival studies in diverse settings.
