||P.334 left column bottom paragraph: "Morphometric analysis revealed that the mean nuclear diameter of endothellial cells was significantly larger than that for type I, type II, and interstitial cells with p<0.01 for all 3 comparisons (table 1). Endothelial cell nuclei had the largest mean caliper diameter of all cells (8.77±1.0 µm SD) and macrophage nuclei were second largest (8.33±0.86 µm SD). Both mean values, however, had variations that were large enough to obliterate a significant difference. The macrophage overall mean nuclear diameter was statistically different from that of type II cells (p<0.01) and had a moderately significant interaction with interstitial cell and type I cell mean nuclear diameters with p=0.1 and p=0.05, respectively. Although type I, type II, and interstitial cell nuclei exhibited no significant difference in mean nuclear diameters between groups, they showed strong internal consistency when a test of significance was performed within each group of 10. This indicates that the mean value determined for each group was the best estimate of each population’s overall mean caliper diameter."
