Effects of omega-3 PUFA on HRV markers in response to short-term exposure to ambient NO2. Effect estimates (95% CI) in HFn (A), LF/HF (B), and VLF (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. HFn: normalized high frequency, IQR: interquartile range, LF/HF: low-to-high frequency ratio, VLF: very low frequency
