Comparison of results gained from previous studies measuring toe systolic pressures

Study	Sample size	Results
de Graaff, et al. (2000) [28]	n = 60	ICC = 0.92 for intra-rater
de Graaff, et al. (2001) [29]	n = 54	ICC = 0.92 for intra-rater
Cloete, et al (2009) [30]	n = 50	ICC = 0.85 for inter-rater ICC = 0.77-0.99 for intra-rater
Scanlon, et al (2009) [31]	n = 60	ICC = 0.78-0.79 for intra-rater ICC = 0.93 for inter-rater

Note: ICC = Intra-class coefficient.
