Two persons in the control arm were determined to be ineligible after they were enrolled and completed some study assessments. Both participants were determined to be ineligible by the principal investigator upon medical record review; the medical records did not provide sufficient documentation of spinal cord injury for the persons they cared for. These individuals are included in our summary of adverse events, but they are not included in other reporting as they were deemed ineligible.

Two persons in the control arm were determined to be ineligible after they were enrolled. Both participants were determined to be ineligible by the principal investigator upon medical record review; the medical records did not provide sufficient documentation to support a spinal cord injury diagnosis for the persons they cared for. Thus, the data for these two participants is not included since they did not meet study eligibility requirements.
