Table 2 Clinical data, laboratory parameters, conventional/Doppler ultrasound and time-intensity curve parameters in early (< 14 days) and late (> 90 days) transplant period groups, including the subset of patients from late group with the lowest creatinine tertile

From: Time-intensity curve analysis of contrast-enhanced ultrasound is unable to differentiate renal dysfunction in the early post-transplant period - a prospective study
