Figure 1.
The classification results for the 29 samples by the first two PCs, where AF and N respectively indicate the pmAF and normal patients; The factor loading (FL) of a PC is defined as the correlation coefficients between original sample variables and this PC.
FL1 and FL2 respectively denote the factor loadings of the first PC and the second PC on the 29 samples.
