Table 3 Change in the albumin-to-creatinine ratio between baseline and 3-month follow-up (n = 26)

From: Consecutive first-morning urine samples to measure change in the albumin-to-creatinine ratio: a pilot study of a home urine collection protocol

Number of urine samples Percentage change in ACR (geometric mean and 95 % CI)
One samplea 15.2 % (−9.2 to 46.1 %)
Average of two consecutive samplesb 24.3 % (2.1 to 51.3 %)
Average of three consecutive samplesc 22.6 % (0.0 to 50.3 %)
