nicely done! thanks for depicting this difference. The only thing - which I guess can be resolved by discussion within panels?! - is what to do when the numbers are not even (like 9 participants in your toy example).

If you don't have treatment switching, as in the above example where patients shift from the antibiotic treatment to surgery after some time, the easiest way to eliminate immortal time bias would be to considers the time point of treatment decision as baseline for all comparisons.

Hi, really interesting video. I am an MSc Epidemiology student. Can you please make an elaborate video on types of regression modelling and their appropriate use? Like which model to use where (depending on study type or the outcome and exposure)? Thanks and keep up the wonderful work!

Hi, I'm the author of dagitty. Thanks for this tutorial! A few tips: - You can also clear the canvas by clicking "Model -> New Model" - After clicking on a variable, you can also type "r" to bring up the "rename" screen

If for lung cancer all three of smoking occupation and anxiety is an ancestor why not for smoking occupation and anxiety are ancestor instead of only anxiety that you mentioned? (6.35)
