Figure 3. Educational attainment is associated with PAL performance in a milestone-related dose response that is different between the sexes.

Linear regression fits (line fill ±95% CI, error bars ± SEM) of the PAL total number of correct from 18 to 85 years old. Lines were split by Educational Attainment level, and the figure was faceted by Sex. For women and men, there were heightened PAL scores per level of Educational Attainment (B_Education = 0.31, p_Education <2e-16, 6 years n = 282, 8 years n = 181, 10 years n = 1177, 12 years n = 5367, 14 years n = 19256, 16 years n = 22942, and 20 years n = 15752).
