Differences between control and GOS groups were stated significant, based on 95% Bayesian credible intervals, which were defined as the 2.5% and 97.5% percentiles of the posterior distributions.
No significant differences between research and control groups were stated in terms of age, time from last menstrual period, duration of hormone replacement therapy, or body mass index (Table 1).
If studies reported significant between-group differences in repeated measures ANOVAs, baseline values between groups were assumed to be different, unless stated otherwise.
Unless otherwise stated, comparisons between groups were analyzed for statistical significance with a one-way Analysis of Variance (ANOVA) followed by Duncans Multiple Comparison post hoc tests, where appropriate, using SPSS 20 for Windows (Statistical Package for Social Scientists Inc., IL, USA).
No differences between groups were found in anxiety-like state, locomotor activity, feeding behavior and spatial orientation task.
Differences between groups were largest for severe health states.
Chi-square analyses found that these differences between groups were statistically significant for two health states in Study 1 and two health states in Study 3. In sum, these findings indicate a greater ceiling effect for caregivers than for non-caregivers across all three samples.
No significant differences of trait or state anxiety between groups were found.
Differences between groups were assessed using ANOVA.
The statistical evaluation between groups was performed, if not stated otherwise, using Kruskal-Wallis.
