Effect of positive emotion training and warm acupuncture on negative emotion and facial nerve in intractable facial paralysis

Table 1 Comparison of baseline data between the two groups of patients, mean ± SD/n (%)

	Control group (n = 60)	Observation group (n = 60)	t/χ2	P value
Age (years)	53.23 ± 11.31	51.69 ± 10.70	0.766	0.445
Gender			0.315	0.575
Male	35 (58.33)	38 (63.33)
Female	25 (41.67)	22 (36.67)
BMI (kg/m2)	23.15 ± 1.37	23.20 ± 1.40	-0.194	0.846
Disease course (months)	5.16 ± 1.05	5.14 ± 1.04	0.078	0.938
Lesion location			0.134	0.714
Left	31 (51.67)	33 (55.00)
Right	29 (48.33)	27 (45.00)

This table compares the baseline continuous variables (age, body mass index, disease course) between the two groups using the independent samples t-test, and compares the categorical variables (gender, lesion location) using the χ². The results show no statistically significant differences between the two groups for all baseline characteristics (P > 0.05). BMI: Body mass index.
