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

Table 4 Generalized estimating equation model results for nutritional trajectories and protocol adherence (n = 250)

Model parameter	Prealbumin (mg/L) β (95%CI)	P value	FTS adherence (yes) OR (95%CI)	P value
Intercept	222.8 (215.4-230.2)	< 0.001	0.82 (0.54-1.25)	0.358
Group (Watson-FTS vs control)	5.48 (2.12-8.84)	0.001	2.15 (1.42-3.26)	< 0.001
Time (categorical reference: T1)
T2 (day 3 for nutrition/adherence)	17.6 (12.4-22.8)	< 0.001	2.56 (1.88-3.48)	< 0.001
T3 (day 7 for nutritional/day 5 for adherence)	33.7 (28.5-38.9)	< 0.001	4.12 (2.95-5.76)	< 0.001
Group × time interaction	6.42 (4.15-8.69)	< 0.001	1.85 (1.18-2.90)	0.008

Data from propensity score matching-matched cohort (n = 125 pairs). Generalized estimating equation models utilized an exchangeable correlation structure. All models were adjusted for the baseline values of the respective outcome and the comprehensive set of covariates listed in Table 1 (including age, body mass index, American Society of Anesthesiologists class, TNM stage, and surgical approach) to account for residual confounding. Interaction odds ratio > 1 or β > 0 indicates a more favorable trajectory in the Watson-fast track surgery group. FTS: Fast track surgery; OR: Odds ratio; CI: Confidence interval.
