Which branch of government do you think receive the most power under the constitution?

In theory, none. There are checks and balances that each can keep watch over the others.

In point of fact or practice, I would say the most powerful is probably the senate. There are 100 members and they can reach consensus easier than the house of representatives and they have more to do about writing laws than does the president. He has more exposure so he looks like he wields a great deal of power, but I think the senate probably has more power.

there is no universal method for handling incomplete data in a clinical trial. each trial has its own set of design and measurement characteristics. there is, however, a set of six principles that can be applied in a wide variety of settings.
