Table 1. Correlations between different predicted log K_ow values and steroid adsorption to different vessels.

R² values from correlations between five different computationally predicted forms of log K_ow and log of steroid retained for the six different vessels, along with the means ± standard deviations of the R² values for each predictive model.
