A mixed model analysis was used to compare changes in mean CV over time to estimate if the dispersion of the repeated measures was not different at each time point.
We used repeated measures analysis (Generalized Estimating Equations) to test for changes in mean resilience over time (Objective 3).
In addition, most studies that have evaluated changes in mean BMI over time have been based on repeated cross-sectional or single-cohort designs [ 6, 8, 12, 17], and few national-level examinations of BMI trajectories over longer time periods have been undertaken in different age groups and different birth cohorts [ 5].
The percentage of tumours that were PR positive and Her-2 positive did not change over time; notably, there was no change in mean score over time for any of the three receptors.
The ciliary beat frequency for each time point was determined by analyzing the change in mean brightness over time in a small area of an individual ciliated cell by fast Fourier transformation using Autosignal 1.7 (SeaSolve Software Inc., San Jose, CA, USA).
In the subset of patients with mild AS at baseline, age (p = 0.0310) and gender (p = 0.0270) had significant interaction with change in mean gradient over time.
In patients with moderate AS, age (p <0.0001), gender (p = 0.0346), renal dysfunction (p = 0.0036), and hyperlipidemia (p = 0.0010) demonstrated significant interaction with change in mean gradient over time.
There was no change in mean CO over time in the control group (4.96 ± 1.21 L/min at 24 hours and 4.76 ± 1.58 L/min at 48 hours).
The t-test was used for the change in mean scores over time (represented in baseline standard deviation units to permit an assessment of effect size [ 31]); smaller change indicates greater reliability, and a difference of >0.5 standard deviation units indicates a minimum detectable difference [ 32].
A negative value for ( {widehat{beta}}_i ) shows that the mean PD for the i th vehicle decreases over time; a positive value indicates that the mean PD increases over time; a close to zero value indicates that there is no change in the mean over time.
