Logistic regression model of radiomic features to predict good lymph node response.

	Correlation Coefficient	Beta Coefficient ± SE	p Value
(Intercept)		−1.26 ± 1.09	0.25
Minimum	0.0045	0.014 ± 0.015	0.35
Skewness	−0.083	−0.49 ± 0.39	0.21
Low Gray Level Run Emphasis	1.20	9.89 ± 7.11	0.16

Good response is >66% and poor response is ≤66% reduction in lymph node volume. Correlation coefficient is the relationship between feature value and percent reduction in lymph node volume. Positive value indicates increase in feature value is correlated with greater percent reduction in lymph node volume. SE = standard error.
