Mediation analyses of NDVI surrounding greenness (binary) and mediators ${\mathrm{NO}}_2$ and ${\text{OP}}^{\text{DTT}}$ (continuous) on the odds of diabetes.

Indicator	Mediator	Proportion mediated (95% CI)
NDVI $300\mathrm{m}$	${\text{OP}}^{\text{DTT}}$	0.27 (0.13, 0.44)
NDVI $300\mathrm{m}$	${\mathrm{NO}}_2$	0.20 (0.08, 0.33)
NDVI $\mathrm{1,000}\mathrm{m}$	${\text{OP}}^{\text{DTT}}$	0.38 (0.22, 0.60)
NDVI $\mathrm{1,000}\mathrm{m}$	${\mathrm{NO}}_2$	0.34 (0.15, 0.53)

Note: Models were adjusted for sex, age, marital status, region of origin, education, work, standardized household income, smoking habits, number of cigarettes/day, alcohol consumption, number of alcohol glasses/week, physical activity, body mass index, and neighborhood socioeconomic status (SES). CI, confidence interval; NDVI, Normalized Difference Vegetation Index; ${\mathrm{NO}}_2$, nitrogen dioxide; ${\text{OP}}^{\text{DTT}}$, oxidative potential (OP) metric with dithiothreitol (DTT) assay.
