Fully hydrogenated canola oil extends lifespan in stroke-prone spontaneously hypertensive rats

Table 3 Statistical analysis of the survival data

	Statistical test	FHCO	Lrd	Plm	Can
Survival (mean ± SEM)		> 180 ± 0	115 ± 6	101 ± 2	94 ± 3
vs. FHCO	Log-rank		<0.001	<0.001	<0.001
vs. FHCO	Wilcoxon		<0.001	<0.001	<0.001
vs. Lrd	Log-rank			0.016	<0.001
vs. Lrd	Wilcoxon			0.053	<0.001
vs. Plm	Log-rank				0.186
vs. Plm	Wilcoxon				0.050

Values represent the mean ± SEM (n = 20/group)
While the log-rank test reflects mostly the late phase of survival curves, the Wilcoxon signed-rank test reflects the early phase
