Estimated effects (coefficients) of p53 and aneuploidy variables in a multinomial logistic regression model.

	Natural log Odds Ratio value (p-value)
	Intercept	p53 +ve	Aneuploidy +ve
Progression	−1.49 (<0.0001)	0.27 (0.63)	1.89 (0.0051)
Missed diagnosis	−2.62 (<0.0001)	1.77 (0.0066)	0.63 (0.46)

Missed diagnosis refers to prevalent dysplasia detected within 12 months from index endoscopy. The intercept values represent the natural log odds ratio values for the two component models (progression vs no progression and missed diagnosis vs no progression, respectively) when both aneuploidy and p53 values are set to zero, i.e. the natural log odds ratios when both aneuploidy and p53 are negative.
