Table 4.

Variance explained by the principal components extracted from the cytokine data.

Component Initial eigenvalues
Total % variance Cumulative %

1 1.96 49.07 49.07
2 1.018 25.56 74.53
3 0.782 19.55 94.08
4 0.237 5.92 100

There were 4 principal components extracted from the data. The percentage of variance in the cytokine data explained by each of the components is given both individually and cumulatively showing that the first 2 components explained the greatest percentages.
