Red Bars Represent Un-Blinded Trial Arms Blue Bars Represent Blinded Trial Arms Yellow Represents Placebo Control Arms from Published Non-Registration trials Green Bars Represent Data from Pivotal Registration Trials The mean percentage symptom reduction was weighted by the number of assigned patients.
