Practical and Statistical Considerations: Adding a statin-intolerant arm would have increased the trial’s complexity, requiring a larger sample size to achieve sufficient statistical power for subgroup analyses.

Instead, the trial prioritized a well-defined population to maximize the clarity of the results.
