Table 1 PICOS (population, intervention, comparator, outcome, and setting) criteria used to perform the systematic review and meta-analyses

From: Comparisons of the effects of different flaxseed products consumption on lipid profiles, inflammatory cytokines and anthropometric indices in patients with dyslipidemia related diseases: systematic review and a dose–response meta-analysis of randomized controlled trials

PICOS

Criteria

Population

Patients with dyslipidemia related diseases

Intervention

Flaxseed products consumption (whole flaxseed, flaxseed oil and lignan)

Comparator

Placebo group/control group

Outcome

Lipid profiles (TC, LDL-C, HDL-C, TG and apo B), inflammatory cytokines (IL-6, TNF-α, CRP and hs-CRP) and anthropometric indices (WC, WHR, Weight and BMI)

Setting

a randomized clinical trial; a randomized crossover study

  1. TC, total cholesterol; TG, triglyceride; LDL-C, low-density lipoprotein cholesterol; HDL-C, high-density lipoprotein cholesterol; apo A, apolipoprotein A; apo B, apolipoprotein B; BMI, body mass index; WC, waist circumference; WHR waist-height ration
