Linear regression adjusted for group, parity, and maternal university education.
Boldface indicates statistically significant differences between variables.
n = 61. Two participants had very high dairy intake compared to the rest of the sample (98 g and 117 g) and influenced the regression (using the full sample, the mean difference in the number of OTUs per gram [95% CI] was 0.9 [0.2, 1.6] OTUs, and the mean difference in the Shannon index per gram [95% CI] was 0.01 [−0.002, 0.02]).
Determined by counting each different fiber-containing food (i.e., grain product, vegetable, or fruit) consumed over the 3 recording days (n = 56).
