Spontaneous ventilation anesthesia combined with uniportal and tubeless thoracoscopic sympathectomy in selected patients with primary palmar hyperhidrosis

Table 3 Association between variables and surgical duration

Surgical duration	Variable	Odds ratio	95% CI	P-value
Crude	Intubation	Ref	0.06–0.45	< 0.001
	SVA	0.16
Adjusted model 1	Intubation	Ref	0.07–0.68	0.008
	SVA	0.23
Crude	Single-port VATS	Ref	1.5–5.3	0.001
	Three-port VATS	2.8
Adjusted model 2	Single-port VATS	Ref	1.02–3.98	0.04
	Three-port VATS	2.02

The association between variables and surgical duration were analyzed using logistic regression models
Adjusted model 1: adjusted age, sex, smoking history and number of surgical port
Adjusted model 2: adjusted age, sex, smoking history and type of anesthesia
