close to significancep = 0.001
Multiple linear regression of the treated segments showed that only pre-injection SPECT levels – both at rest and stress – were significantly or close to significance correlated with post-injection SPECT, either at rest ( p = 0.001 vs. pre-injection SPECT levels at rest and p = 0.0003 vs. pre-injection SPECT levels at stress) and stress ( p = 0.076 vs. pre-injection SPECT levels at rest and p = 0.041 vs. pre-injection SPECT levels at stress).
