Figure 2.

Figure 2

IICV vs. Conversion status with local smoothing trend (LOESS). Data are jittered around conversion status to better illustrate data densities. Figure 2a includes participants with MCI and those who were cognitively healthy at baseline (N=349). Figure 2b includes only those individuals with MCI at baseline (N=244).

Notes:

IICV: Intra-Individual Cognitive Variability. Used raw IICV score for comparison. Conversion is a dichotomous variable: Converters vs. Non-converters. The trend line is smoothed using LOESS in order to illustrate the relationship between conversion and IICV score without linearity assumptions. Additionally, IICV scores are jittered to more clearly see the number of participants obtaining individual IICV scores.
