Urinary ELISA of set 2. Urinary levels of ApoC3 (a, d), Igfbp3 (b, e), and ApoD (c, f) in set 2 (13 AD, 5 MCI, and 32 control urine samples) as measured by ELISA. Crude levels (a–c) and Cre-adjusted levels (d–f) of the three proteins. p values were calculated using the Mann-Whitney U test. Data are presented as median and interquartile range. AD, Alzheimer's disease; ApoC3, apolipoprotein C3; ApoD, apolipoprotein D; Cre, creatinine; ELISA, enzyme-linked immunosorbent assay; Igfbp3, insulin-like growth factor-binding protein 3; MCI, mild cognitive impairment.
