Fig. 1. —Bar chart shows changes in size of metastases in patients with (white bars) and without (black bars) hepatic capsular retraction. Note moderately strong correlation between capsular retraction and decrease in size ( = 0.46, p < 0.05). Correlation between retraction and increase in size of metastases is not as strong ( = 0.32) but remains statistically significant (p < 0.05). There is significant correlation between capsular retraction and increase, decrease, or overall change in size.
