Table 1 Clinical characteristics of the study population and of groups defined by TG/HDL-C quartiles. [Continuous variables are presented as mean ± standard deviation, categorical variables as absolute N and (%); * = P value only for comparison of Quartile IV vs. Quartile I].
Study population n = 355 | Quartile I < 1.305 n = 89 | Quartile II 1.305–2.095 n = 89 | Quartile III 2.129–3.384 n = 88 | Quartile IV > 3.384 n = 89 | P value for trend | |
