The concentrations of 4 identified serum miRNAs in Alzheimer's disease (AD) cases and nondementia controls (NC) enrolled in the training and validation sets. The absolute concentrations of the 4 identified serum miRNAs in 48 AD and 48 NC of training set (a–d), as well as 79 AD and 75 NC of the validation set using a RT-qPCR assay (e–h). The absolute concentrations of the miRNAs were calculated based on the standard curves. Each point represents the mean of triplicate samples. Each P value was derived from a nonparametric Mann-Whitney U-test.   ∗∗∗ P < 0.001.
