This figure shows the number of participants with one or more cognition measurements (from T0 up to T20 (time in years)) through rounds 2–6 of the Doetinchem Cohort Study (DCS) during the 20-year follow-up. Note: This figure includes all participants with cognition measurements in the DCS. In the present study, part of these participants were excluded (see Supplementary Fig. 1). T0 = blue, T5 = green, T10 = gray, T15 = orange, T20 = yellow.
