Pooled estimates for the increase in mortality associated with an increase of 10μg·m^-3 in nitrogen dioxide (NO₂; average of lags 0 and 1 of the 1-h maxima of NO₂), adjusting alternatively for the other pollutants (average of lags 0 and 1)

Data are presented as % increase (95% confidence interval). CVD: cardiovascular disease; BS: black smoke; PM₁₀: particle matter with a 50% cut-off aerodynamic diameter of 10 μm; SO₂: sulphur dioxide; O₃ 8-h: maximum daily 8-h O₃concentration.
