All of it is Greek to me, but it seems to be referring to Chris's apparent infatuation with models, his new favorite drug, and his heart rate reaction to the model/drug combo.
"ANAVEX3-71 at the studied doses did not have a clinically relevant effect on heart rate ... . ANAVEX3-71 alone was retained in the primary model (Nell?) due to small fit differences (bikinis?) between models."
What scandal rag was this piece of cheap titillation (titulation?) printed in, anyway?!
(The FDA is not going to be amused by this NONSENSE!!)
