Boxplots showing the distribution of LE8 and LC9 scores across LS7 score levels. Boxplots illustrate the distribution of Life’s Essential 8 (LE8, panel A) and Life’s Crucial 9 (LC9, panel B) scores across different levels of Life’s Simple 7 (LS7). Pearson correlation coefficients indicate a strong positive relationship between LS7 and LE8 (r = 0.91, P < 0.001) and between LS7 and LC9 (r = 0.89, P < 0.001)
