Comparison of neointimal thickness, residual lumen area, internal elastic lamina area, and neointimal area among the groups of miniature pigs. (Data were presented as mean ± standard deviation (SD). A-D represent neointimal thickness, residual lumen area, internal elastic lamina area, and neointimal area, respectively.) Note: * indicates marked differences versus the S1 group (P < 0.05); # indicates drastic differences versus the D0 group (P < 0.05) (in Figs. 1, 2 and 4)
