The positive and negative predictive values (PPV and NPV) - simply explained

[@abbasatashdehghan58]

Thank you for your very clear explanations. They were the best I've had ever seen among the videos on TH-cam.
It would be good to insert the link to the next videos, if any, in the description as sometimes it is difficult to find them
