| Participants, n | 1,204 | 1,290 | |
| Median, servings/wk | 0 | 0.56 | |
| Model 1 | 0 | 4.9 (−2.8, 13.2) | 0.22 |

Model 1 was adjusted for age at blood collection (continuous). Model 2 included the covariate in model 1 and was in addition controlled for race (white, nonwhite), BMI (continuous), physical activity (continuous), alcohol consumption (continuous), total caloric intake (continuous), smoking status and pack-years (never, past smoker and pack-years < 20, past smoker and pack-years ≥ 20, current smoker and pack-years < 20, current smoker and pack-years ≥ 20), and case–control status in previous nested case–control studies. Model 3 was in addition adjusted for total n–6 fatty acids. All models reflect linear regression.
Yes or no refers to reported consumption of canned tuna or dark meat fish.
White or light canned tuna fish in water (drained solids).
Dark meat fish includes mackerel, salmon, sardines, bluefish, and swordfish.
