Short-term outcomes of laparoscopic sleeve gastrectomy among obesity patients in the northern west bank: a retrospective records review

Table 6 Multivariate linear regression model for the association of the main study outcome (post-operative BMI) with marital status, practice of sport or exercise and age variables (N = 30) ^§

	Post-operative BMI
Independent variables	B	SE	Beta	P- value (95% CI for B)
Age (years)	0.17	0.12	0.23	0.18 (−0.83-0.42)
Marital status (not married/married)	1.84	2.97	0.11	0.54 (−4.28-7.95)
Practice any kind of sport or exercise currently (no/yes)	−7.33	2.60	−0.47	0.009 (−12.68- -1.98)*

^§Variables entered in the model are those with a P- value <0.05 in univariate analysis. SE, standard error; B, Unstandardized regression coefficient; Beta, Standardized regression coefficient; CI, confidence interval; BMI, body mass index [(weight (kilogram) divided by the square of height (meter)]. *Statistically significant (p <0.05). Enter regression method was used.
