For infants who received any amount of breast milk for any duration, the univariate SOR was statistically significant at 0.40 (95% confidence interval [CI]: 0.35– 0.44, I2 = 71%). Multivariable ORs were reported for only 7 of the studies and the multivariable SOR was statistically significant at 0.55 (95% CI: I2=40%). studies provided information about any breastfeeding at 2months of age or older. The summary univariable estimate for the 3 studies was 0.38 (95% CI: 0.27– 0.54; I2= 78%). Because only There may be some confusion over the interpretation of I2. Authors state There was no heterogeneity (I2=40%) (Multivariate analysis of breast feeding versus no breastfeeding) but the developers of this approach state that a value of 0% indicates no observed heterogeneity, and larger values show increasing heterogeneity.
