CogDiss 1188X,

Not a slam dunk about confounding but regulators did not allow SOC/placebo into the trial after the hold. Sure seems to me they saw something in 2015 that pushed them in that direction and crossover confoundment could not have been a contributing factor to that decision or SOC/placebo would have very likely been allowed to continue unless the gap was still huge. Goes back to regulators probably seeing shipping records as well as the sequestered NWBO employee(s). Best wishes.
