Footnote a in the abstract is incorrect as written (as far as I can tell). Your values are consistent with treating this as a 2-tailed distribution, but the footnote describes the size of one tail. In your notation, to be consistent with the quoted numerical values, the footnote should read: 2*(1-\Phi(x)) = r, or x = \Phi^{-1} (1-r/2).
