Summary of eligibility criteria for study inclusion in the systematic review

Domain	Inclusion criteria
Population	Adults (≥18 years) at high‐risk of cardiovascular disease who attended an individual face‐to‐face consultation with a dietitian in a primary health‐care setting
Intervention	Individual face‐to‐face consultations provided exclusively by a dietitian with an aim to lower cardiometabolic risk factors. The dietetic consultation was defined as at least one face‐to‐face session with a dietitian aimed at supporting an individual patient to modify dietary behaviours and could include any or all components of the dietitian's nutrition care process; assessment, diagnosis, intervention, monitoring and evaluation. Exclusions were interventions delivered to patients in hospital, via the telephone only, in a group or lecture setting, or by a multidisciplinary team where the influence of the dietitian could not be determined
Comparator	Usual care, where patients received usual medical care from a physician or nurse; minimal care, where patients received nutrition‐related printed material plus or minus general dietary information from a nurse; or control, where no nutrition intervention was provided. If a study had multiple study arms, only those that met the inclusion criteria were included in the review and meta‐analyses. Further detail on comparator criteria have been published previously10
Outcome	Clinical measures were specifically blood lipid concentrations (total cholesterol (TC), LDL cholesterol (LDL‐C), HDL cholesterol (HDL‐C) and triglycerides (TG). Studies needed to state blood lipid moderation as an aim and/or primary outcome in the management of cardiometabolic risk factors. For inclusion in the meta‐analyses, studies needed to report at least one of the defined blood lipid concentrations at baseline and post‐intervention
Study design	Systematic reviews of randomised controlled trials; and randomised controlled trials using parallel design
