Intra-rater reliability of the 6-min walk test in people with liver cirrhosis

Table 4 One-sample t-test comparing mean differences in distances walked between the two 6-min walk tests with zero difference

Variable	One-sample t-test compared with the zero constant
	Mean (m)	SD (m)	n	SE (m)	Constant	t-value	df	P value
6MWT-2 - 6MWT-1 (m)	-14.4	26.7	19	6.1	0.0	-2.34714	18	0.03

6MWT-2: Second 6-min walk test; 6MWT-1: First 6-min walk test; df: Degree of freedom; SD: Standard deviation; SE: Standard error.
