Parameters of straight line fit to Mitochondrial Energy Score data

Straight line fit results
Slope	0.132± 0.012	Observed t-test	11.4
Intercept	−0.123± 0.042	Degrees of freedom	69†
R2	0.645*	t-test probability, P	< 0.001

^*R² (called the “coefficient of determination” or the “explained variation”) is the square of the product moment correlation coefficient.

^†There are 71 data points and 2 parameters, slope and intercept.
