A computer program for comparing survival experience of two groups after adjustment for relevant covariates

Area of Science:

• Biostatistics
• Medical Informatics
• Survival Analysis

Background:

• Comparing survival between patient groups is crucial for clinical research.
• Existing methods may require advanced statistical knowledge.
• Accurate survival analysis informs treatment strategies and patient outcomes.

Purpose of the Study:

• To present a novel computer program for evaluating survival differences between two patient cohorts.
• To implement and integrate established survival analysis techniques, including Mantel and Hankey-Myers methods.
• To provide an adjusted survival curve analysis accounting for prognostic variable distributions.

Main Methods:

• The program utilizes life table analysis, stratifying data by prognostic variables.
• It computes an adjusted survival curve for one group relative to another.
• Cumulative survival curve plots are generated for optional visualization.

Main Results:

• The developed program effectively evaluates survival differences between patient groups.
• It provides adjusted survival curves, offering deeper insights into prognostic variable impact.
• The software facilitates the application of complex statistical methods in survival analysis.

Conclusions:

• The computer program offers a valuable tool for researchers conducting survival analysis.
• It simplifies the comparison of survival data and the assessment of prognostic factors.
• This approach enhances the understanding of patient survival dynamics in clinical studies.
