first aid vs kaplan = biostats ODDS RATIO - zen786 - ArchivalUser - 04-08-2012
first aid 2011 pg. 52 states:
odds ratio = A/B
................._____
................. C/D
Kaplan 2010 edition pg. 12 states:
odds ratio = A/C
................______
................ B/D
but they both state at the end : AD/BC
either one of them is really dumb at basic algebra or one is a massive error...
