The control arm received standard of care (SOC): instructions to complete the mandated LKD follow\u2010up consisting of a health questionnaire and laboratory measurements at 6 months, 1 year, and 2 years post\u2010donation. The intervention arm received SOC and was mailed a $25 gift card for each timely completed follow\u2010up. Compliance rates were compared at each timepoint using Poisson regression.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 175 donors consented to participate.
