Associations between categories of combined exposure to road traffic noise at the most exposed façade and the least exposed façade (${\mathrm{L}}_{\text{den}}$) at the residence (10-y mean) and risk of filled prescriptions for antihypertensive medication. {N cases [IRR (95% CI)].}

Least exposed façade	Most exposed façade
	${\mathrm{L}}_{\text{den}}$ $<53$ dB(A)	${\mathrm{L}}_{\text{den}}$ 53–65 dB(A)	${\mathrm{L}}_{\text{den}}$ $>65$ dB(A)
${\mathrm{L}}_{\text{den}}$ $<45$ dB(A)	3,736 [1.000 (ref)]	2,453 [0.971 (0.922, 1.023)]	579 [0.989 (0.901, 1.085)]
${\mathrm{L}}_{\text{den}}$ 45–51 dB(A)	2,891 [0.952 (0.906, 1.000)]	4,452 [0.980 (0.939, 1.022)]	880 [0.969 (0.901, 1.041)]
${\mathrm{L}}_{\text{den}}$ $>51$ dB(A)	54 [0.924 (0.684, 1.249)]	4,566 [0.968 (0.927, 1.011)]	1,043 [1.045 (0.976, 1.119)]

Note: Model was adjusted for sex, calendar year, level of education, disposable income, cohabitation, area-level proportion of low income, low education and unemployment, smoking status, smoking duration, smoking intensity, alcohol intake, abstainers, sport during leisure time (yes/no), sport (hours/week), vegetable intake, and fruit intake. CI, confidence interval; IRR, incidence rate ratio; ${\mathrm{L}}_{\text{den}}$, indicator of overall noise levels during day, evening, and night.
