Expressions of MMPs and TIMP-1 in Gastric Ulcers May Differentiate H. pylori-Infected from NSAID-Related Ulcers
Figure 2
Box plots of the distributions and median scores of MMP-7, and -9 and TIMP-1 in the superficial epithelium of gastric ulcer tissues and nonulcer tissues in different groups, respectively. The values compared scores according to patients in the H. pylori-infected, NSAID-related, and combined H. pylori-infection and NSAID-use groups by Mann-Whitney test, and also compared scores according to ulcer tissues and nonulcer tissues by Wilcoxon signed-rank test. In the box plots, the 75th and 25th percentiles are represented by the top and bottom of the box, respectively. The horizontal lines refer to the medians. Abbreviations are as in Figure 1.
