Figure 4: (a) The correlation between AD and the duration of administration of dutasteride. AD: artery/arteriole density, . (b) The correlation between AA and the duration of administration of dutasteride. AA: artery/arteriole area as a proportion of the whole area. . (c) The correlation between VD and the duration of administration of dutasteride. VD: vein/venule density, . (d) The correlation between VA and the duration of administration of dutasteride. VA: vein/venule area as a proportion of the whole area. . Data for BPH tissues in the control group are plotted as duration 0. values are for the Spearman’s rank correlation test. A least squares regression line was drawn for each panel.
