Model inputs were kept the same as in the original analysis.
Model inputs were kept the same as in the original analysis, except that the white matter disease cut-off changed to greater than 1 out of 9 points.
Model inputs were kept the same as in the original analysis, except that the white matter disease cut-off changed to greater than 3 out of 9 points.
Model inputs were kept the same as in the original analysis, plus additional terms for baseline log10(interleukin-6 level), baseline log10(C-reactive protein level) depressive symptoms, income level and physical activity.
