Figure 3. r2 analysis of 10 unmodified QSPRs: Goodness-of-fit analyses of measured vs. predicted permeation coefficients (log kp values). These equations include 1. Fujiwara et al. (2003)[18]; 2. Mitragotri (2002)[22]; 3. Moody and MacPherson (2003)[19]; 4. Moss and Cronin (2002)[2]; 5. Potts and Guy (1992)[23]; 6. Geinoz et al. (2004)[1]; 7. ten Berge (2009)[20]; 8. USEPA (2004)[24]; 9. Vecchia and Bunge (2002)[25]; and 10. Cleek and Bunge (1993)[21]. QSPR: Quantitative structure-permeation relationship; QSAR: quantitative structure-activity relationship.
