Association of Watson-based humanistic fast track surgery with stoma colorectal cancer recovery: A propensity matched study

Table 5 Multivariable regression analysis for predictors of postoperative recovery quality (n = 312)

Predictors	Model 1 early recovery success (flatus < 48 hours)			Model 2 functional status at discharge (KPS)
	Adjusted OR (95%CI)	χ2	P value	Adjusted β (95%CI)	t value	P value
Watson-FTS intervention (ref: Routine)	3.62 (2.18-6.01)	24.15	< 0.001	6.24 (4.85-7.63)	8.82	< 0.001
Age (per year)	0.97 (0.94-0.99)	5.02	0.025	-0.08 (-0.16 to 0.01)	-2.14	0.033
BMI (kg/m2)	1.04 (0.96-1.13)	0.88	0.348	0.12 (-0.15 to 0.39)	0.86	0.391
Laparoscopic approach (ref: Open)	2.45 (1.34-4.48)	8.24	0.004	2.85 (1.12-4.58)	3.24	0.001
ASA class III (ref: I-II)	0.78 (0.45-1.35)	0.76	0.383	-1.45 (-3.12 to 0.22)	-1.71	0.088
TNM stage III (ref: I-II)	0.82 (0.51-1.32)	0.64	0.424	-3.12 (-5.45 to 0.79)	-2.63	0.009

Model 1 utilized multivariable logistic regression (Hosmer-Lemeshow, P = 0.742). Model 2 utilized multivariable linear regression (adjusted R squared = 0.485). Reference groups are indicated in parentheses.

KPS: Karnofsky Performance Status; BMI: Body mass index; ASA: American Society of Anesthesiologists; OR: Odds ratio; β: Unstandardized regression coefficient; CI: Confidence interval.
