Statistical methods / analysis
The median change in IMS associated with substantial, small and no change on the global rating of change will be compared using a Kruskal-Wallis test.
Distribution based methods used to calculated the MID will be the SEM and the effect size. The SEM is defined as s"1"v(1-r) , where s1 is the standard deviation at baseline (admission to ICU) and r is the test-retest reliability obtained from a previous study. One SEM closely approximates the MID. The effect size quantifies the amount of difference between two means on a unit less scale. A moderate effect size is considered clinically important and is calculated as 0.5 X standard deviation of the change scores from ICU admission to ICU discharge.
