In the paper by Sekikawa et al. (“Associations of equol‐producing status with white matter lesion and amyloid‐β deposition in cognitively normal elderly Japanese. Alzheimer's Dement. 2020; 6:e12089. https://doi.org/10.1002/trc2.12089), errors occurred in the preparation of the paper for publication, requiring the following corrections.
In the second paragraph of the Results section, the unit of measure in the sentence beginning “Among 45 non‐producers…” should be corrected. The “median (interquartile range) serum level of daidzein” should be “82.3 (37.9 to 315.1) nmol/L” rather than “82.3 (37.9 to 315.1) μmol/L.”
In addition, the units in the first column of Table 2 should also be corrected from μmol/L to nmol/L. A corrected version of Table 2 appears below.
TABLE 2.
Serum levels of equol, daidzein, and genistein in all participants and by equol‐producing status 6 to 9 years before the imaging study
| All participants | Equol non‐producer | Low producer | High producer | |
|---|---|---|---|---|
| (n = 91) | (n = 45) | (n = 23) | (n = 23) | |
| Equol, nmol/L | 4.3 (0, 48.7) | 0 | 22.8 (9.2, 31.4) | 166.1 (109.0, 256.4) |
| Daidzein, nmol/L | 94.4 (35.3, 247.0) | 82.3 (37.9, 315.1) | 51.8 (23.6, 87.6) | 134.1 (110.6, 250.5) |
| Genistein, nmol/L | 276.6 (86.7, 522.1) | 276.6 (61.1, 586.6) | 161.4 (73.9, 219.4) | 358.6 (288.7, 647.6) |
Notes: Values are expressed as median (interquartile range).
Equol non‐producers and producers were defined as participants whose serum levels of equol were 0 or > 0, respectively. Using the median of serum equol levels among equol producers, equol producers were further divided into low (≤ the median) and high producers (> the median).
The authors regret the errors.
