SECONDARY outcome

Timeframe: Change from baseline quality of life score at 1 week for each study arm

Population: Because the plan was to administer the intervention as a single dose, the investigators determined that the KDQOL should be removed from the study design because it is an evaluation used to assess changes over time. This decision was made prior to enrollment of any participants and was not administered to any study participants; however, the measure was not removed from the registration at that time.
