Figure 2

Association of splice site strength, expression level and RIF. Panels (A) and (B): Frequency of retention as a function of Shapiro and Senapathy scores (donor + acceptor). (C) and (D): Frequency of retention as a function of expression levels (1306 low-RIF and 203 high-RIF events for which there was SAGE data). Average expressions per gene were used. The insets show the log transformed data and the lines are the least squares regression fits. ρ = Spearman rank order and R=Pearson linear correlation coefficients (on log data). Note that the linear regression fittings should be taken only as an indicator of the tendency, rather than formal data fitting.
