aThe dental care score comprised number of dentist visits per year, frequency of teeth cleaning and use of floss. The oral health score accounted for wearing dentures, age at which patient started to wear dentures and frequency of gum bleeding. Composite scores and mouthwash were grouped into two categories. Here, an OH score of 6–7, a DC score of 3–6 and mouthwash use ≥ 2/d served as the exposure, ensuring that the categories included a meaningful number of subjects
