Fig. 1From: Exercise in claudicants increase or decrease walking ability and the response relates to mitochondrial functionTreadmill walking performance in the whole group (n = 28, grey) and subgroups of positive (n = 8, white) and negative responders (n = 8, black) a claudication onset time. b peak walking time. Values are mean and standard error of the mean. p values are calculated by paired t test within groups and analysis of covariance (ANCOVA) between subgroups of negative and positive responders. *(p < 0.05), **(p < 0.01), ***(p < 0.001)Back to article page
