Of note, the patients aged 35–50 were all men. Therefore, we moreover performed subgroup analyses of male patients stratified by age (Additional file 2: Table S1). A significant difference was observed for the EPA/AA ratio, but not DHA/AA.
The female patient characteristics stratified by age are shown (Additional file 2: Table S2).
Correlation between n-3 PUFAs and age at ACS onset
The Pearson correlation analysis showed that age at ACS onset was positively associated with the EPA/AA and DHA/AA ratios in all (Fig. 1) and male patients (Additional file 1: Figure S2).
