    Self-controlled case series (SCCS) designs address time-invariant confounding but struggle with time-varying confounding, impacting study validity.

  • 2

    Active comparators can mitigate time-varying confounding in SCCS by providing a reference treatment with a similar confounding pattern.

  • 3

    The article formalizes methods for incorporating active comparators in SCCS, comparing regression coefficients or using nested regression models.

  • 4

    Two case studies illustrate these methods: thiazolidinedione use and fractures, and fluoroquinolone use and uveitis, using UK Clinical Practice Research Datalink data.

    Recommendations are provided for researchers to enhance the design and interpretation of SCCS studies using active comparators.
