Thanks Idit. I must be recalling a slide at a Pfizer investigators meeting about F/U data tracking the same patients. Masterlongevity has it correct, I think, in that the effect resolved sometime after six months and the declines in both populations (treatment vs. control) paralleled eachother from 6 months on. Pfizer presented the data as ultimately providing the patient with an extra 440 days before their ultimate demise.
