What if you could run a clinical trial… without randomizing anyone?

You’ll learn:

  • Why observational studies are biased by default
  • How propensity scores balance treated vs untreated groups
  • The 4 major methods (matching, weighting, stratification, adjustment)
  • When they work… and when they fail
