Randomization Study subjects will be randomized to treatment or control group and then further to an outpatient or inpatient admission subset. Randomization will be determined based on a randomization code devised by the University of New Mexico General Clinical Research Center (GCRC) statistician, and this randomization process will be administered by a GCRC staff person such that Drs. Sloan and Colleran, the investigators involved in the biological aspects of the study, will be blinded to the randomization.
