Table 4. Univariate survival analyses of FCM-DNA and ICM-DNA for different DNA ploidy category definitions.

	FCM-DNA			ICM-DNA
Category definition	Log rank value	P-value	Hazard ratio (95% confidence interval)a	Log-rank value	P-value	Hazard ratio (95% confidence interval)a
A	2.9	0.09		10.1	0.001	2.3 (1.4–3.9)
B	5.5	0.06		13.8	0.001	1.0 (0.3–3.1)
						2.4 (1.4–4.2)
C	5.3	0.02	1.8 (1.1–2.9)	13.8	<0.001	2.4 (1.5–4.0)
D	NA			16.8	<0.001	2.8 (1.7–4.7)

Abbreviations: FCM-DNA, DNA ploidy status measured using flow cytometry; ICM-DNA, DNA ploidy status measured using image cytometry; NA, not applicable.

Same category definitions as in Table 2. The column hazard ratios of category definition B shows two values. The first value is the hazard ratio of the DNA tetraploid category compared with the DNA diploid nearest ratio category, and the second value is the hazard ratio of the DNA aneuploid category compared with the DNA diploid category.

^aHazard ratio is only presented when significant (confidence interval does not contain 1), and represents values to reference group (i.e., favourable outcome).
