FIG. 1.

Gastrointestinal symptoms. Median scores from the Gastrointestinal Symptom Rating Scale (GSRS) for five categories of symptoms and all combined are plotted for placebo (n=7) and probiotic (n=9) groups. Subject GAN 009 was excluded because survey information was not provided for two study visits. The maximal value on the y-axis is the highest possible score on the GSRS. Asterisks indicate probiotic group significant differences from week 0 (paired Student's t-test); there were no significant differences from week 0 in the placebo group. Comparisons of placebo versus probiotic groups showed significant differences only for the constipation category at week 8 (p=0.049) and the combination of all symptoms at week 8 (p=0.049).
