Correlation between the 10m walk test speed and the length of hospital stay, intensive care unit stay and duration of mechanical ventilation

Variable	Walk test time		Difference
	Post-ICU	Pre-discharge
Length of hospital stay (days)	rs = -0.625; p < 0.001	rs = -0.272; p = 0.090	rs = 0.478; p = 0.002
Length of ICU stay (days)	r = 0.060; p = 0.715	r = 0.175; p = 0.279	r = 0.212; p = 0.190
MV duration (days)	rs = -0.374; p = 0.017	rs = -0.203; p = 0.209	rs = 0.166; p = 0.306

ICU - intensive care unit; MV - mechanical ventilation.
