P-values presented are adjusted for clinic. Message effect = Effect of enhanced message independent of drug. Drug Effect = Effect of montelukast independent of message type. The interaction P-value evaluates for whether the drug effect is modified by the message effect
Baseline mean and difference from baseline are based on ordinal scale score of 1 to 9, strongly disagree to strongly agree, 5 is neutral.
