Table 8 Analysis results of generalized estimating equation

Variables	β	SE	Wald χ²	P value	OR (95%CI)
Constant (baseline)	-1.832	0.412	19.799	< 0.001	-
Time = day 3	1.284	0.298	18.518	< 0.001	3.61 (1.99-6.54)
Time = day 7	0.634	0.277	5.243	0.022	1.89 (1.10-3.27)
Surgical approach (total gastrectomy)	0.742	0.315	5.55	0.018	2.10 (1.14-3.87)
High risk factors (yes)	0.615	0.294	4.371	0.037	1.85 (1.04-3.31)
Time × surgical method	-	-	8.362	0.015	-
Time × high risk factors	-	-	7.851	0.02	-

P < 0.05 indicated significant difference. The model analyzed repeated binary measurements (effusion presence/absence) across postoperative day 1, 3, and 7. β: Coefficient estimate; OR: Odds ratio; CI: Confidence interval.
