Table 8 Descriptive statistics and association analysis of astigmatism vector components.
From: Association of nutritional intake with myopia and astigmatism
Variable | Definition | Mean (SD) [D] | β (per 1000 mcg) | 95% CI | P |
|---|---|---|---|---|---|
J0 (Orthogonal) | Quantifies WTR/ATR astigmatism (0°/180° meridians) | −0.028 (0.477) | 0.00128 | 0.342018 | 0.546 |
J45 (Oblique) | Quantifies oblique astigmatism (45°/135° meridians) | −0.009 (0.263) | 0.00103 | (−0.0013, 0.0034) | 0.378 |
D, diopters; WTR, with-the-rule; ATR, against-the-rule; β, regression coefficient per 1000 mcg lutein intake; P, p-value for statistical significance; 95% CI lower, lower bound of the 95% confidence interval; 95% CI, 95% confidence interval. | |||||
