The OR in the upper left 22 table is incorrect, which should be 6 (726/36*2 =6), not 1. This means the OR of "ate cookies" does not change after stratification by "drank milk", so "drank milk" is not a confounder, and "ate cookies" is independently asso w/ EHEC outbreak.

On the other hand, OR for "drank milk" changed a lot (from 3.9 to 1.0), which indicates "drank milk" might be a confounder and, therefore, is not independently asso w/ EHEc outbreak.

English is not my first language, but would it be possible that adherence is not equivalent to adhesion and somehow interchangeable to aggregation? I feel like doing a reading comprehension test, not USMLE.

wuagbe  Several genetics questions on NBME20 appear to be trying to throw us off by changing the descriptions of inheritance, leaving us to assume incomplete penetrance, smh. +

Just wondering if someone could explain the difference between collagen and elastin for this one? I thought either or could be used for tensile strength. Anyone have clarification, don't know why collagen is the best answer!

notyasupreme  Lol, never mind I realize, it's a scar and that's type III collagen! +2  
meryen13  type III is whats usually present but then it gets replaced by collagen I in the scar tissue to add more strength. +  
i_hate_it_here  It is also the disulfide bonds that add to tensile strength of collagen, while the inter-chain fibril cross-linking that leads to elastins elasticity FA2020 pg: 51&52 +  
xw1984  I think the Q emphasized postoperatiive. Maybe the production of elastin does not increase much comparing to collagen. +  
topgunber  i think they would refer to elastin in cases of arteriolar compliance +
