Relationships between the size of region at risk and the size of myocardial infarction. Linear regression analysis showed that the infarct size was unrelated to the size of the risk region in all groups. Linear regression equations: SHAM group, 𝑦=0.02301𝑥−0.08, 𝑟=0.23, 𝑃>0.05; I/R group, 𝑦=0.1151𝑥+8.4, 𝑟=0.33, 𝑃>0.05; VER group, 𝑦=0.05201𝑥+5.767, 𝑟=0.29, 𝑃>0.05; TGC group, 𝑦=0.1115𝑥+4.86, 𝑟=0.38, 𝑃>0.05.
