ing also resulted in (P=0.0003) 21% reductions at endpoint, compared to baseline. However, TG and apo B concentrations were not affected by consumption of the control diet at endpoint, compared to baseline.

Additional analysis was performed on a subset of data where values outside the range of two standard deviations were removed form the original data set. The treatment effects on each parameter at midpoint and endpoint remained unchanged using ANOVA.

Cholesterol absorption and synthesis rate in response to treatments

No treatment effect was observed in ABS in week 6 with and without outliers being removed from the original data set. However, slightly lower ABS levels were noted as a result of L. fermentum feeding, compared to L. reuteri treatment (ABS=379.83 36.87 and 384.38 32.14 per milhr for L. fermentum and L. reuteri feeding, respectively). Furthermore, L. fermentum feeding resulted in a slightly smaller increase in ABS, compared to L. reuteri treatment; however, the difference between L. fermentum and L. reuteri feeding in ABS relative to control, was not significant (L. fermentum=46.48 23.88 % relative to control treatment; L. reuteri=55.73 34.02 % relative to control treatment).

There was no difference across treatments in FSR (FSR = 11.73 1.80; 10.33 1.85; 11.67 1.75 %, for L. fermentum, L. reuteri and control treatment, respectively). However, once the outliers, which are outside the range of plus and/or minus two standard deviations, were removed, L. fermentum treatment resulted in a higher (P=0.0169) FSR value, compared to L. reuteri feeding. Although there was no difference in FSR between L. fermentum and control treatments, L. reuteri resulted in a lower FSR value, compared to control (P=0.0112, obtained by Least Squares Means).

Fecal bile acid in response to treatments

There were no differences noted across three treatments in fecal bile acid concentrations in week 6 (fecal bile acids= 33.28 2.12; 32.26 2.13; 30.93 2.44 mol/g dry feces, for L. fermentum, L. reuteri and control treatment, respectively). In addition, no treatment effect in fecal acid levels was identified when outliers were further removed from the original data set. However, a slightly greater percent increase in fecal bile acid concentrations relative to control was observed in response to L. fermentum, compared to L. reuteri treatment, although the difference between L. fermentum andL. reuteri was not significant (L. fermentum=19.15 9.82 % relative to control; L. reuteri=13.77 9.44 % relative to control treatment).

Body weight and body compositions in response to treatments

There were no differences in body weight of subjects at baseline or endpoint across the three treatments.

In terms of body composition analysis, since ethics approval for conducting DEXA scans was not granted until February 4, 2008, only 28 subjects were available to undergo whole body scans over the course of the study. As a result, endpoint scans of all three phases were obtained from a smaller subgroup of subjects (n=15). Among these 15 subjects, eleven subjects received scans at baseline and endpoint for L. fermentum treat本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
