Effect of whole-grain intake on myopia stratified by sex and age (Adjusted OR and 95% confidence intervals)
| Proportion of whole-grain intake | P-trend | |||
|---|---|---|---|---|
| < 25% | 25–50% | > 50% | ||
| Sex | ||||
| Female | 1 | 1.663 (0.767–3.604) | 0.214 (0.049–0.938) * | 0.390 |
| Male | 1 | 0.739 (0.347–1.573) | 0.209 (0.045–0.979) * | 0.169 |
| Age | ||||
| 6–8 years | 1 | 0.903 (0.429–1.898) | 0.412 (0.113–1.494) | 0.239 |
| 9–12 years | 1 | 1.413 (0.663–3.010) | 0.196 (0.044–0.872) * | 0.115 |
The reference category was whole grain (WG) intake < 25%
Multivariable logistic regression was used to estimate the association between WG intake and incidence of myopia. When stratified by sex and age, all elements were adjusted in the models, except for themselves
