Hyperbaric oxygen with muscle relaxation for sleep quality anxiety and depression in post-gastric cancer sleep disorders

Table 2 Comparison of sleep quality between the two groups, mean ± SD/n (%)

	PSQI total score (points)		Shortened sleep latency	Improved sleep efficiency
	Before treatment	After treatment
Control group (n = 48)	18.28 ± 1.63	7.35 ± 1.12	28 (58.33)	30 (62.50)
Observation group (n = 48)	18.13 ± 1.75	4.25 ± 0.64	40 (83.33)	42 (87.5)
t/χ2	0.435	16.614	7.261	8.000
P value	0.665	< 0.001	0.007	0.005

This table compares sleep quality indicators (Pittsburgh Sleep Quality Index scores, shortened sleep latency, improved sleep efficiency) between the two groups before and after treatment. Continuous data were analyzed using independent samples t-test, and categorical data were analyzed using χ² test. The results showed that after treatment, the observation group had significantly lower Pittsburgh Sleep Quality Index scores, higher rates of shortened sleep latency and improved sleep efficiency than the control group (P < 0.05).
