Unit of blood flow velocity: cm/s. * Comparison among three groups: Non-PICCRT, asymptomatic PICCRT, and symptomatic PICCRT. Non-PICCRT vs. asymptomatic PICCRT, Fintergroup*time=15.368, P<0.001; symptomatic PICCRT vs. asymptomatic PICCRT, Fintergroup*time=25.664, P<0.001; symptomatic PICCRT vs. non-PICCRT, Fintergroup*time=4.564, P<0.001. | |||||
