Fig 2 Prevalence of AD (as a percentage) within the first 18 months of life according to domestic water hardness in the municipality of birth. Each data point represents the prevalence of AD among children born in one municipality or several municipalities with the same degree of domestic water hardness (within 1 decimal of °dH; 1°dH = 17.85 mg/L).
