Figure 2

Regression plots showing how the independent variables affect the SDNN (1st row), and pDec and SDDec (2nd row) when the infant was in the incubator. Each column reflects an independent variable, as annotated on the x-axes. The y-axes show the values of the HRV features after suitable transformation. Statistically significant (p-value < 0.05) variables are in red.
