Small intestinal contents supernatant viscosity in animals fed either cellulose or HPMC. Values are shown as box plots, with n=10-12 for each group. The horizontal line within each box represents the median and the boundary of the boxes indicates the 25th and 75th percentile of the data. Error bars indicate 10th and 90th percentiles. Circles above or below the error bars indicate outlying data points. Values were log transformed prior to statistical analysis by one-way analysis of variance. Values not sharing a common letter are significantly different (p<0.05).
