Note: “Inert”, a placebo characterized as something traditionally inert (e.g. Sugar pill, sham treatment); “Active”, a placebo characterized as something traditionally considered active (medical intervention, drug); “n/a”, a placebo definition that does not fall into either the “Inert” or “Active” category.
