Sensitivity, Specificity, PPV & NPV | BIOSTAT | USMLE STEP 1

* At 14:28 to 14:32 I said what are the chances that 'disease' is actually positive from all the positive results. it should be the chances that 'TEST' is actually positive from all the positive results. slip of tongue , so keep that in mind.
* If you are first or second year medical student or if you have more than one year to prepare for USMLE Step 1 or any other exam then I strongly recommend you to watch Dr. Najeeb lectures to make your concepts very clear. If you don't have enough time to prepare for USMLE Step 1 then I would not recommend you to go through all the videos of Dr. Najeeb . Just watch Neurology and Immunology.
