Among beneficiaries with epilepsy, separate scatterplots of antiseizure medication (ASM) proportion of days covered (PDC) (x-axis) vs each non-ASM PDC (y-axis). Each plot contains a Spearman correlation coefficient (r), sample size (N), and a superimposed regression line with 95% confidence interval and regression equation. Note that selective serotonin reuptake inhibitors are not included due to space constraints, but results are similar to displayed panels (r = 0.50, 95% CI 0.49–0.51, N = 24,738). HTN = antihypertensive; Levo. = levothyroxine; PPI = proton pump inhibitor.
