Effects were estimated for studies grouped according to setting (high income countries, low or middle income countries, and the United Kingdom), intensity (= 5 planned contacts), and timing of peer support (postnatal period with or without antenatal care), and analysed using metaregression for any and exclusive breast feeding at last study follow-up.
