Table 3.

Statistical testing of model scenarios: here ‘model’ refers to the NC targeting model and ‘null’ refers to model representing the null hypothesis (see §2); the comparison (r²) is between modeland experiment; ‘all’ refers to comparison across all organs and ‘lung’ refers to comparison for lung alone. (* indicates the activated form of cells.)
