Malassezia

inflammatory bowel disease

Malassezia is an interesting but still moderate-confidence signal in inflammatory bowel disease.

Malassezia shows a moderate evidence base in inflammatory bowel disease, with multiple central papers and additional supporting literature.

Why this scores the way it does
  • moderate central evidence base
Main caveats
  • directionality and confounding still require curated review
