Table 4:

Comparison of rCBF among the three FAIR images in the area with more prolonged TTP (dTTP ≥3.2 s)^*

Comparison	MD	P Value	95% CI
FAIR 800 vs FAIR 1200	−0.026	<.05	−0.049-−0.002
FAIR 800 vs FAIR 1600	−0.078	<.001	−0.101-−0.054
FAIR 1200 vs FAIR 1600	−0.052	<.001	−0.075-−0.029

Note:—MD indicates mean difference; CI, confidence interval; FAIR 800, TI = 800 ms; FAIR 1200, TI = 1200 ms; FAIR 1600, TI = 1600 ms.

^*Statistical analysis was performed with the repeated measures ANOVA and post hoc analysis with the Tukey-Kramer multiple comparisons test.
