So, in order to get you in the mood as it were

We all have a choice.

That's always possible when you're doing these types of studies.

Disciplines.

Type of study versus a true experimental design.

It doesn't really matter if you're in the north, the south, the east, the west.

So you can think of this in those terms.

There are 170 clinical trials investigating the role of stem cells in heart disease.

Maybe it would inform clinicians around the world on how to improve on the clinical management of HlV patients.

We couldn't get at the causal mechanism just by doing correlations and correlations and correlations.

And they very helpfully tell you how to go and find the paper.

Last segment we talked about the power of randomized experiments.

As a particle physicist, I study the elementary particles and how they interact on the most fundamental level.

Examination?

But they lack the power of randomized experiments, and I'd like to show you.

I want to contrast that now. With, observational studies.

An experiment is when we have random assignment conditions and something is minipulated in independent variable.

He was still, as ever, deeply attracted by the study of crime, and occupied his immense faculties and extraordinary powers of observation in following out those clues, and clearing up those mysteries which had been abandoned as hopeless by the official police.

Without randomized experiments, without random assignment to conditions, we can never really be sure.

And the clinical methods that we've got aren't very good at studying that because they are based on the idea of person to person interaction.

My diary

Hi. Welcome to Statistics One. This is the first lecture where we'll talk about randomized experiments and observational studies.

You know other people more then you know yourself

And we've set up charities that will help us fund the clinical research to determine the best treatment practice now and better treatment into the future, so we don't just sit on our laurels and say, Okay, we're doing okay.

How low can you sink?

Every year or so,

So what we've got is a situation.

Now it's a pity they can't capture that look, craig, that clinical look.

They won't matter which part we take.

if children have interest then education happens.

But remember, go back to lecture one, where we made the distinction between randomized controlled experiments and observational studies.

One of which he compared to chess, which is theoretical elegant cosmology, which is very precise and clean.

What kind of shit research are you doing?

Local governments need to set up effective systems for reviewing the ethical issues around the clinical trials which are authorized in different developing countries, and they need to do this by setting up ethical review committees that are independent of the government and research sponsors.

I've been part of an exceptional team at InSightec in Israel and partners around the world for taking this idea, this concept, noninvasive surgery, from the research lab to routine clinical use.

There's now a new research project underway at the Karolinska in Sweden to prove that hypothesis.

Of a drug that Dr. Bell created in '81

So the data that we collect for prostate cancer or for Alzheimer's trials goes into silos where it can only be used for prostate cancer or for Alzheimer's research.

You watch?

I'm doing research for an article...

The first of these is informed consent.

And to point out the power of this these animals are able to get to that platform just as fast as animals that have seen their entire lives.

This is happening today.

How many masks do you need?

I presided over so many scenes like this.
