I heard this phrase in a radio advertisement:
In a recent medically supervised anecdotal study, over 96% of the participants
who took Product X*, reported an increase in libido and erectile strength.
What is a medically supervised anecdotal study?
Why not have a real clinical trial of Product X?
Probably because a real clinical trial would show Product X
is no better than the potions and elixirs sold at 19th century medicine shows.
