OBJECTIVE: Given participants' research literacy is essential for clinical trial participation, evidence-based strategies are needed that improve literacy and easily accessed online. We tested whether an infographic letter-that illustrated how dropouts can distort study conclusions-improved participant knowledge about the impact of dropouts relative to a control letter.
