Baseline (visit 1) characteristics of ARIC participants according to quartiles of plasma lactate.

*The ranges of the plasma lactate quartiles were determined using specimens from the weighted random cohort sample.†Represents the maximum number of participants in each category. Actual number may vary due to missing data.‡Plasma lactate mg/dL may be converted to mmol/L by multiplying by 0.111.§P-trend evaluated with linear or logistic regression using the median lactate value for each quartile as an ordinal variable.∧There were no participants with coronary heart disease in quartile 1. SE not calculated due to small sample size.**Represents geometric mean and interquartile range.Note: LDL represents low density lipoprotein. HDL represents high density lipoprotein.
