Table 3 Principal component analysis (PCA) correlation matrix

From: Short-term perinatal oxygen exposure may impair lung development in adult mice

Component 1
Correlation in gene expression among groups (4-week old mice)
 21%O2 Group 0.981
 40%O2 Group 0.995
 100%O2 Group 0.994
Correlation in gene expression among groups (12-week old mice)
 21%O2 Group 0.981
 40%O2 Group 0.997
 100%O2 Group 0.991
  1. Cell cycle gene expression in whole lung homogenate in 4- and 12-week-old mice following short-term (30 min) of perinatal oxygen exposure soon after birth. The principal component analysis revealed one component with Eigenvalue > 1. The PCA component matrix demonstrates a high correlation between each variable in 4- and 12-week-old mice
