Fig. 2From: The influence of dietary intake of omega-3 polyunsaturated fatty acids on the association between short-term exposure to ambient nitrogen dioxide and respiratory and cardiovascular outcomes among healthy adultsEffects of omega-3 PUFA on blood lipids in response to short-term exposure to ambient NO2. Effect estimates (95% CI) in total cholesterol (A), HDL (B), and LDL (C) were calculated relative to an IQR increase in NO2 concentrations at lag 0 to 4 days, as well as 5-day moving average in the low and high omega-3 groups. * p < 0.05 for significant association within a group. HDL: high-density lipoprotein, IQR: interquartile range, LDL: low-density lipoproteinBack to article page
