What groups have the financial means to get chest x-rays, and what groups do not? What historical events could create the circumstances where different groups have different health outcomes?
you ain't gonna like the truth but there are differences between the races and during med school they try to say it ain't so but once you start seeing patients there's differences in musculature/skin, all sorts. and if you have a good attending they tactfully tell you and you go 'was it in a study?' and nope nobody wants to publish it. and no i'm talking just stuff like scabies or diabetes.
