Hypothesis
How can we efficiently create event-time tables for epidemiological studies?
Conclusion
The new methodology supports the creation of efficient and readable programs for making event-time tables.
Supporting Evidence
- The methodology allows for simultaneous analysis of multiple outcomes.
- The macro is designed to handle various time-varying factors efficiently.
- Event-time tables are crucial for accurate epidemiological analysis.
Takeaway
This study shows how to make tables that help researchers track events over time in health studies, making it easier to analyze data.
Methodology
The study provides a tutorial on using a SAS macro to create event-time tables, focusing on stratification by various factors.
Potential Biases
Potential bias may arise from the handling of time-varying covariates.
Limitations
The methodology may require significant computing resources for large data sets.
