Table 3. Beta coefficients and 95% confidence intervals (CIs) from multivariable linear regression analysis used to examine the associations between measure of infant growth with measures of alpha-diversity. Models adjusted for birth weight and birth length. P-values in bold denote statistical significance for p-values <0.05.
