Assessment of the Variation Associated with Repeated Measurement of Gastrointestinal Transit Times and Assessment of the Effect of Oral Ranitidine on Gastrointestinal Transit Times Using a Wireless Motility Capsule System in Dogs
Table 1
Summary of GI transit times in healthy dogs measured using the WMC system before and during treatment with ranitidine. % CV = coefficient of variation. Between-subject and within-subject coefficients of variation were calculated based on measurements taken prior to treatment with ranitidine. P values are for testing the null hypothesis that transit time does not differ among the 4 repetitions (3 before treatment with ranitidine and the 4th during treatment with ranitidine). *: nonparametric data, transit times for the 4 repetitions were compared using a Friedman’s test; **: parametric data, transit times for the 4 repetitions were compared using a repeated measures ANOVA.
