Estimated associations of increase of air pollution and glomerular filtration rate.

*Model was adjusted for age, sex, clinical variables including obesity, atrial fibrillation, hyperlipidemia, diabetes mellitus and arterial hypertension. The lag-model for each day was estimated separately.

Abbreviations: CI, confidence interval; NO₂, nitrogen dioxide; PM_2.5, particulate matter with a diameter of 2.5 μm or less; PM₁₀, particulate matter with a diameter of 10 μm or less; SO₂, sulfur dioxide.
