Figure 1

Reproducibility of percent density from the raw image representation. This shows the percent density measure (PD) applied to a sample of 80 raw images at two time points labeled as PD1 and PD2, respectively (diamonds) evaluated with this relationship PD2 = m ×PD1 + b, where m and b are the slope and intercept. The fitted line (solid) was estimated with regression analysis giving: m = 0.96 ± 0.05, b = 0.76, and linear correlation = 0.92.
