Linear regression analysis included gestational age per week, birth weight in 100 g steps, gender, multiple birth, maternal descent and exposure to Bifidobacterium infantis/Lactobacillus acidophilus probiotics. Linear regression analysis included gestational age per week, birth weight in 100 g steps, gender, multiple birth, maternal descent and exposure to Bifidobacterium infantis/Lactobacillus acidophilus probiotics. The effect of probiotics on weight gain as g/d growth rates in mm/d is shown as B coefficient, 95% confidence interval and p-value. Adjusted R2 values indicate coefficients of determinations and adjust for the number of terms used in the model.
