Hi Profesor! I must point out, that this video about study design was very helpful, however I am confused, regarding a study that is required before and after design (I believe its called pre-post design). In which group of studies is this design included? And can you please explain a little bit more about it. Thank you very much. Good day :)

Thank you very much. It was clear and to the point. Keep up the Good work.

I finally got these clarified, thanks heaps!

Hello. I conducted a study 4 groups where. I measured impact of glass of water and image quality in certain medical exam. I took an image, gave them a glass of water and took another one, to measure image quality improvement.
Is it a pre - post test study design?
Or randomized control study? I performed this test on 103 random patients. Which 51 consecutive patients was first group, (image 1, image 2, water, image 3),
43 of them (received water, and took image 1 and image 2.)
The rest had extra images to see how water behaves inside of the patient. Help me to clarify.

For case control, you said that a con is that it lacks temporality, and as an example you said we don't know how long they've been smoking. But before that you said in a case control, we can ask about their smoking habits, such as how long they've been smoking. Can you explain this discrepancy...?

your lecture is one of the most comprehensive courses online

The kid outro is priceless. ❤

you the best thank you
