  1. P: patient number, S: time-point (t0, t1, t2) related sample number (V0, V1, V2), n.d. not determined, at V0, the patient did not produce any additional saliva after stimulation. n.m. not measurable: at low concentrations, Fe test kits showed diffuse colors or discrepancies and these cases were excluded as not reliable.
