Fig. 4

Thrombus weight, size, and vein recanalization rate on days 14 and 28. (a) Original magnification, × 100. Representative thrombus sections stained with hematoxylin and eosin in C, D, ED, and IED groups. Scale bar: 200 μm. Thrombus weight (b), thrombus size (c), and vein recanalization rate (d) are shown. Thrombus size is expressed as a percentage of the total vein lumen area, while recanalization rate is calculated as a percentage of the area of the vein lumen. All values represent the mean ± SD (n = 4–5 mice). Data were analyzed using ANOVA (*P < 0.05, **P < 0.01, ***P < 0.001).C: Control group; D: DVT group; ED: exercise and DVT group; IED: SIRT1 inhibitor, exercise DVT group
