if you are asking about the where are these definition’s they are from uworld step 2 and there are tables in the extra section in these card , I didnt change a card that was already there , I copied the moderate persistent card and made another card for the mild persistent asthma , used the copy method to keep the same organization of the card and for the tables that are found in the extra section
i went and checked Amboss (since i dont remember the questions ID) it is also mentioned in Amboss , in the asthma article under Assessment of severity heres the link for it https://next.amboss.com/us/article/Ph0WVf#531iQg0
