Key

Effect direction

Upward arrow ▴= positive health impact

Downward arrow ▾= negative health impact

Sideways arrows ◂▸= no change/mixed effects/conflicting findings

Sample size

Large arrow ▴ > 25 individuals in the intervention group

Medium arrow ▴ = 15 15 to 25 individuals in the intervention group

Small arrow ▴ < 15 individuals in the intervention group

Risk of bias

= low risk of bias

= some concerns

= high risk of bias

Certainty of evidence (GRADE)

⊕⊕⊕⊕ = High

⊕⊕⊕○= Moderate

⊕⊕○○= Low

⊕○○○= Very low.
