Table 2 Inclusion/exclusion criteria applied in abstract and full-text screening1

From: Hierarchies of evidence applied to lifestyle Medicine (HEALM): introduction of a strength-of-evidence approach based on a methodological systematic review

1) Criteria used in abstract screening
Included exposures/interventions
• Diet
• Exercise
• Stress or stress reduction
• Social relationships
• Addiction(s)
• Sleep
• Genetic-based factors
Excluded exposures/interventions:
• Pharmaceutical-based interventions
• Studies on research methods (e.g., validation of a health questionnaire), medical devices, tests or other assays
• Supplement interventions (e.g., micronutrient supplements, protein supplements) without accompanying lifestyle modifications
• Genome-wide association studies (GWAS, i.e., an analysis comparing the allele frequencies of all available polymorphic markers in unrelated patients with a specific symptom or disease condition, and those of healthy controls to identify markers associated with a specific disease or condition)
• Target population is children or healthcare workers
2) Additional criteria used in full-text screening
Included strength of evidence (SOE) tools that evaluated one of the following outcomes:
• Longevity
• Vitality and healthy or successful aging
• Disease risk or disease incidence
Excluded SOE tools addressed outcomes related to:
• Disease prevalence
• Injury severity
• Efficacy or effectiveness of diagnostic tools, medical devices, or other assays
  1. 1 The inclusion/exclusion criteria were used during abstract/full-text screening to identify potentially relevant articles that may include relevant SOE tools
