The pooled prevalence of dyslipidaemia in the general population from population-based studies was 25·5% (95% CI 20·0–31·4; corrected from 23·6%, 18·4–29·6) for elevated concentrations of total cholesterol with a cutoff of at least 5·2 mmol/L, 37·4% (29·4–45·7; corrected from 41·1%; 33·0–49·2) for low concentrations of HDL cholesterol with a cutoff of less than 1·0 mmol/L, 28.6% (15·8–43·5; corrected from 25·7%, 16·2–36·6) for elevated concentrations of LDL cholesterol with a cutoff of at least 3·3 mmol/L, and 17·0% (11·9–22·7; corrected from 16·5%, 11·8–21·6) for elevated concentrations of triglycerides with a cutoff of at least 1·7 mmol/L (table).
