Interaction between calcium channel blockers and capecitabine in colorectal cancer patients with hypertension

Table 2 Comparison of blood pressure control before and after treatment, mean ± SD

Group	Systolic blood pressure (mmHg)		Diastolic blood pressure (mmHg)
	Before treatment	After treatment	Before treatment	After treatment
Control group (n = 60)	153.63 ± 5.19	126.42 ± 9.43	96.44 ± 3.72	82.69 ± 2.97
Experimental group (n = 60)	153.60 ± 5.29	119.04 ± 10.44	95.83 ± 3.92	78.90 ± 4.23
t value	0.025	4.064	0.877	5.685
P value	0.980	< 0.001	0.382	< 0.001

It compares the systolic and diastolic blood pressure levels before and after treatment in both groups using the independent samples t-test. The results show that there was no significant difference in baseline blood pressure between the two groups (P > 0.05), while both groups showed significant post-treatment blood pressure reduction, with the experimental group demonstrating a greater decrease (P < 0.001).
