The treatment effect of each spray was calculated in reference to use of water, which is known to improve oral dryness so the magnitude of the treatment effect may be underestimated, however, we would expect both products to be affected equally."},"pointOfContact":{"email":"amf91@pitt.edu","organization":"University of Pittsburgh","phone":"4126479665","title":"Anne Fisher"}}
