Independent clinical characteristics associated with NGS tuft volume in both kidney donors and patients with renal tumor up to age 75 years

Clinical CharacteristicMultivariable Adjusteda
Kidney Donors and Patients with Renal Tumor (n=2447)

  • The mean SD across both populations was used (9.6 cm for height, 5.3 kg/m2 for body mass index [BMI], 19.5 ml/min for eGFR).

  • a Adjusted for each other characteristic.

  • b If 24-hour urine protein was excluded, findings were similar except hypertension was also associated with larger NSG tuft volume (6.2% larger; P=0.002).
