Would you be surprised to learn that the graphical representations of association (RR, HR, OR) are seriously flawed not just in some but in most of the peer-reviewed articles published in JAMA, The Lancet and NEJM in 2008? I certainly was. Read about it in The Lancet at "Graphical Presentation of Relative Measures of Association". Apparently, rather than improving communication an awful lot of graphics are actually "distorting what the data have to say".
