Abbreviation: CI, confidence interval.

Note: A linear model log10yij=α+β1ti(j1)+β2xiti(j1)+ϵij with an autoregressive (AR-1) covariance matrix was used. α denotes the overall average log-volume at the time of randomization, β1 is the linear change in log-volume across time for the reference group (WT, IgG1-b12 4 mg/kg, Vehicle), while β2 is the difference between the linear change in log-volume across time between the reference group and a comparison group (K164R, AXL-107-MMAE 2 mg/kg, AZD6244), ϵij~N(0,σ2) and ρ is the autocorrelation between adjacent measurements.
