- The life-table method is a standard technique for survival analysis.
- Complex calculations can be a barrier to widespread use.
Purpose of the Study:
- To simplify the calculation of the life-table method of survival analysis.
- To provide an accessible tool for survival data analysis.
Main Methods:
- A microcomputer spreadsheet template was developed.
- The template performs life-table survival calculations.
- It includes the log-rank test for statistical comparisons between patient groups.
Main Results:
- The template accurately performed life-table calculations.
- Log-rank test comparisons were validated against standard statistical software.
- The template demonstrated reliability and efficiency.
Conclusions:
- The developed template simplifies life-table calculations.
- It is suitable for long-term follow-up of patients in interventional radiology.
- This tool enhances the accessibility of survival analysis in clinical practice.
