My interpretation of the underlying study is that 53.4% of the asian women who developed cancer in the study were nonsmokers, which I believe is subtly different from what you said.

But I think what NBC wrote on the graph is pretty unambiguous, that 53.4% of nonsmoking asian women in the study developed cancer. They titled the graph "Lung cancer among nonsmokers, by race" when it should really be "Nonsmoking among Lung Cancers, by race".

Or do you think between the title, caption, and data, their chart is presented in a way that can be argued is correct? It doesn't seem like it to me.
