Adjusted beta coefficients and their 95% confidence intervals (CI) for Chao1 indices versus retinal microcirculation outcomes in the total population (n = 177, purple), boys (n = 89, green) and girls (n = 88, orange). Models were adjusted for exposure counterpart (bacteria/fungi), BMI, mean arterial blood pressure, education of the mother, black carbon concentrations, proportion of high green around the residence and duration of settled dust sampling. CRVE: central retinal vein equivalent; CRAE: central retinal arterial equivalent, TI: tortuosity index.
