reached borderline significanceP =0.051
The mean infarct volume at 48 hours (Table 4 ; Figure 2 B) did not significantly differ in RIC+ mice compared with RIC− mice in the unadjusted analysis (27.8 versus 32.5 mm3; mean difference, −4.7 [95% CI, −10.2 to 0.9]; P =0.097), but this difference reached borderline significance in the sex-stratified analysis ( P =0.051).
