Streptococcus

type 2 diabetes

Streptococcus looks like a credible signal in type 2 diabetes, though some caution is still warranted.

Streptococcus shows a strong literature footprint in type 2 diabetes, with substantial central evidence and broader supporting literature.

Why this scores the way it does
  • strong central evidence base
  • meaningful supporting human literature
  • substantial preclinical support
Main caveats
  • directionality and confounding still require curated review
