Interpreting PubMed Results

When reviewing PubMed studies for Methylene Blue and Parkinson's, key considerations include:

  • Study design hierarchy: RCTs > cohort studies > case-control > case reports > animal studies > cell culture
  • Sample size: Small studies (n<50) should be interpreted cautiously
  • Conflict of interest: Check funding sources
  • Replication: Single studies should not change treatment decisions
