Dietary intakes of isoflavones at cohort baseline: tertile medians and cut-points in ethnic/racial groups ab
| Racial/Ethnic Group | Tertile 1 | Tertile 2 | Tertile 3 |
|---|---|---|---|
| Median (Upper and Lower Bounds) | Median (Upper and Lower Bounds) | Median (Upper and Lower Bounds) | |
| Black | 78 (3 – 134) | 222 (136 – 397) | 850 (413 – 135102) |
| White | 98 (11 – 181) | 329 (182 – 654) | 1575 (668 – 72566) |
| Chinese | 1553 (27 – 3889) | 6691 (3958 – 10007) | 20518 (10129 – 118252) |
| Japanese | 3987 (288 – 8184) | 15899 (8705 – 24393) | 36358 (25884 – 89106) |
| Aggregated, Asian groups | 1751 (27 – 5633) | 8851 (5723 – 15932) | 29113 (16147 – 118252) |
| Aggregated, non-Asian groups | 88 (3 – 161) | 286 (161 – 584) | 1230 (584 – 135102) |

Baseline tertile cut points were maintained throughout longitudinal analyses. Aggregated Asian and non-Asian tertiles were used for relational analyses, because the distribution of isoflavones was extremely bimodal (see Methods).
