Each plot contains three components: the distribution of the phenotype (bell curve), the index score of each individual patient (circles) and the LOESS fit of the index value as a function of phenotype (regression curve). In each of four panels, the abscissa represents each patient’s LDLc:HDLc ratio. The ordinate indicates the index value for the LOESS curve. The p-value is derived from a linear analysis associating the index and clinical variable, and the n indicates the number of samples considered in the analysis. Correction for the comparisons of each index to five phenotypes in this study (LDLc, HDLc, LDLc:HDLc, triglycerides and BMI) requires multiplication of the respective p-value by a factor of five.
