Thank you for your videos. They are truly appreciated. You help me understand the material far better than when it's covered in the class lectures.

Thank you very much, if you have time, two questions, what 1 thing did you really like about it, and when you say more, what more, there are video lectures on the other 3 key types of study designs, randomised controlled trials, and ecological and cross-sectional studies.

Around 21 minutes, should that not be 0.29 deaths per two years?

Hi, nice spot, technically yes but in practice no. This is because the whole study period is seen as the unit of time (the time period for the risk). Otherwise we would have lots of different risk estimates depending on what years we selected. In the example, if we just looked at Year 1 the risk is 1/7, in Year 2 1/7, and in Year 1 + 2 it is 2/7. This is the reason why the rate estimate, in person-years give the more accurate estimate of the probability (chance) of dying because it takes into account, the number of people who died, the number of people who were exposed at the beginning, and the years of exposure. While risk only includes the number of people who died, and the number of people who were exposed at the beginning. This is why risk is easier to understand and use, but less accurate than rate, which is more accurate but harder to understand because person-years is not a idea we can intuitively understand and make sense of. It's not a concept we can link to everyday life.
