Stratified analysis of the association of total omega-3 PUFAs and the risk of EC recurrence. All the HRs were adjusted for age, bmi, and stage in cox regression with Firth’s Penalized Likelihood, P-trend values were obtained by treating ordinal omega-3 PUFA as continuous in cox regression models in subgroups. Interaction test was conducted by entering the cross product of total omega-3 PUFA and the variables of interest. P < 0.05 was considered as significant
