Participant Flow

Study participants were recruited between June 2018 and February 2022 from the Renal Clinics at the University of Iowa Hospital and Clinics (UIHC) and the Iowa City Veterans Affairs Health Care System (VA HCS). All procedures were approved by the University of Iowa and the Iowa City VA HCS Institutional Review Boards and conducted in accordance with the Declaration of Helsinki. All participants provided written documentation of the informed consent process before study participation.

SECONDARY outcome

Timeframe: 12 months

NIH toolbox battery- Executive Function Age-Corrected Standard Score is reported (T-score): This score compares the score of the test-taker to those in the NIH Toolbox nationally representative normative sample at the same age, where a score of 100 indicates performance that was at the national average for the test-taking participant's age. Age-corrected standard scores were derived separately for children (ages 3-17) and adults (ages 18-85). A score of 115 or 85, for example, would indicate that the participant's performance is 1 SD above or below the national average, respectively, when compared with like-aged participants. Higher scores indicate better performance.
