Key result
Resting hyperemia decreased in a pressure-dependent manner during blood flow restriction (NOBFR > 40BFR > 80BFR, p < 0.001), but blood flow increased above baseline following exercise.

p-value: p=<0.001
Blood flow restriction during low-load exercise reduces hyperemia in a pressure-dependent manner, although blood flow still increases above baseline post-exercise.
Mouser et al. (2017) reported an RCT. Blood flow restriction vs. No restriction (NOBFR) was evaluated on Blood flow response (resting hyperemia) (p=<0.001). Resting hyperemia decreased in a pressure-dependent manner during blood flow restriction (NOBFR > 40BFR > 80BFR, p < 0.001), but blood flow increased above baseline following exercise.
