  1. Hey John,

    Love your collection of CPR’s here. I’m prepping for the OCS and was taking a look at this CPR. It looks like the one you have depicted is just the first article by Cai. The factors are completely different from the Fritz study. Why did you choose to post the ones by Cai? Thanks!
