Summary of findings for the main comparison. Restriction of pacifier use versus no restriction for increasing duration of breastfeeding

Pacifier use versus pacifier restriction for increasing duration of breastfeeding

Patient or population: healthy full‐term newborns whose mothers have initiated breastfeeding and intend to exclusively breastfeed
Settings: multi‐centre trial carried out at 5 tertiary centres in Argentina
Intervention: restricted pacifier use

Comparison: no restriction in pacifier use

*The basis for the assumed risk (e.g. the median control group risk across studies) taken from the included studies. The corresponding risk (and its 95% confidence interval) is based on the assumed risk in the comparison group and the relative effect of the intervention (and its 95% CI).
CI: Confidence interval; RR: Risk ratio.

GRADE Working Group grades of evidence
High quality: Further research is very unlikely to change our confidence in the estimate of effect.
Moderate quality: Further research is likely to have an important impact on our confidence in the estimate of effect and may change the estimate.
Low quality: Further research is very likely to have an important impact on our confidence in the estimate of effect and is likely to change the estimate.
Very low quality: We are very uncertain about the estimate.

1 Evidence obtained from only one study and so downgraded for imprecision
