Differences Between the Three Methods of Placement Time, Repositioning Time, and Total Time

Category	Traditional Over-Bed Method	Postural Trolley-Assisted Over-Bed Method	Direct Over-Bed Method	H	P
Placement time* (min)	4.80[4.38,5.27]	1.48[1.32,1.73]	1.55[1.42,1.71]	87.36	<0.001
Repositioning time* (min)	4.56[4.03,4.89]	2.81[2.53,3.31]	3.01[2.87,3.59]	133.21	<0.001
Total time* (min)	9.28[8.47,10.16]	4.25[3.88,5.03]	4.48[4.32,5.31]	162.45	<0.001

Notes: *None of them conformed to a normal distribution; there was an irregularity in the variance; therefore the Kruskal–Wallis test was used.
