Key Limitations of MAIC Analyses
Author(s):
A panelist discusses how Matching-Adjusted Indirect Comparison (MAIC) analyses are limited by potential unmeasured confounding factors, small effective sample sizes after matching, and reliance on published aggregate data, which should be carefully considered when interpreting findings as complementary rather than definitive evidence for treatment decisions.

Summary for Physicians: Limitations of MAIC Analyses
MAIC analyses, although useful, have several important methodological limitations:
- Potential unmeasured confounding factors may still bias results despite matching procedures.
- Effective sample sizes are often substantially reduced after matching, limiting statistical power.
- Reliance on aggregate published data rather than individual patient data introduces additional uncertainty.
When reviewing MAIC analyses, consider these findings as complementary evidence rather than definitive proof for treatment decisions. These analyses should be interpreted within the broader context of available clinical evidence.
