¹Values are means ± SDs or %, as appropriate. The cut-off values for DII tertiles were: 0.46 points (maximum of tertile 1) and 1.18 points (maximum of tertile 2). DII, Dietary Inflammatory Index; IADL, instrumental activities of daily living; SU.VI.MAX, Supplémentation en Vitamines et Minéraux Antioxydants.

² P values are based on Cochran-Mantel-Haenszel tests (for categorical variables) or linear contrast tests (for continuous variables).
