Estimates and confidence interval for the fixed-effect “location” and the end point minimal blood velocitya

Estimate SD 95% CI T P
(Intercept) 12.6067 0.59 (11.44–13.78) 21.24 <0.001
I 0.81 0.57 (−0.32–1.94) 1.4 0.16
III 4.75 0.56 (3.64–5.86) 8.4 <0.001

Location II is taken as base. This means that the estimate of the increase/decrease from I (respectively III) to II is calculated by comparing the blood velocity at segment I (respectively III) with the blood velocity at segment II (Intercept).
