Component

HDL cholesterol concentration

HDL cholesterol concentration. The model and exposure of each linked claim define its scope.

4 recorded relationships. Experimental role, claim status and evidence remain attached to each record.

How nutrients influence it

Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.

How nutrients reach it in more than one step

Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

  1. Oat beta-glucan in doses at or above 3 grams per day reduced low-density lipoprotein and total cholesterol relative to control by 0.25 mmol/L with 95% CI 0.20 to 0.30 and 0.30 mmol/L with 95% CI 0.24 to 0.35 respectively, there was no significant effect on high-density lipoprotein cholesterol or triglycerides and no evidence that dose across a range of 3.0 to 12.4 grams per day or duration of treatment from 2 to 12 weeks influenced the results, and LDL cholesterol lowering was significantly greater with higher baseline LDL cholesterol.
