Key Points

  • This research aims to examine the effects of using continuity corrections in meta-analyses of sparse data.
  • Conducted sensitivity analysis using various summary methods and continuity correction factors.
  • Evaluated imbalances between study arm sizes to determine estimation impact.
  • Spanning estimates varied significantly with and without continuity corrections.
  • Sensitivity analysis highlights the importance of choosing appropriate methods for accurate results.

Abstract

Many routinely used summary methods provide widely ranging estimates when applied to sparse data with high imbalance between the size of the studies' arms. A sensitivity analysis using several methods and continuity correction factors is advocated for routine practice.
