Table II.

Difference in Venous Clinical Severity Scores (VCSS) between patients with combined reflux in the great saphenous vein (CSV) and the saphenofemoral junction (SFJ) vs those with isolated reflux in the CSV

Analysis	Number of patients	Difference in VCSS (with GSV + SFJ reflux vs GSV reflux alone)		95% confidence interval		P-value	Interpretation
Analysis	Number of patients	Difference	SE	Low	High	P-value	Difference^c	Equivalent^d

Crude^a	352	−0.21	0.26	−0.73	0.30	.42	Not significant	Yes
Adjusted^b	346	−0.35	0.28	−0.89	0.19	.20	Not significant	Yes

Crude: VCSS score = f(SFJ reflux).

Adjusted: VCSS score = f(SFJ reflux, age, sex, race, ethnicity, body mass index).

A difference is significant if the confidence interval excludes 0 (ie, P < .05).

A difference is equivalent if the 95% confidence interval excludes both −1 and +1.
