 Standardized odds ratio (OR) is the change in odds for a standard deviation (in controls) increase in image features; the 95% confidence intervals are in brackets. Sum average 16, 32 and 64 are the texture feature sum average using images downsized by a factor of 16, 32 and 64
 The Δχ
^{2} and p values refer to likelihoodratio tests on whether there is a significant difference between screendetected and interval cancers (i.e. significance of interaction terms)
