Salivary levels of amyloid beta reflect brain amyloid beta burden in cognitively-normal older adults.

However, because some of the correlations to total protein were close to significance, we also normalized Aβ levels to the total protein in each sample in the analyses carried out below. 3.2.

However, we did not detect significant correlations between saliva Aβ species and total protein measurements and given that the Aβ correlations to FBP SUVR remained highly significant when value were corrected for total protein, argues against a reduced flow-rate contributing to the observed effect.
