Test 2 vs 1		59.5 (22.4) (95% CI 9.7 to 109.2)		47.5 (18.4) (95% CI 6.6 to 18.4)
Test 3 vs 1		74.3 (18.8) (95% CI 32.5 to 116.1)		60.3 (16.2) (95% CI 24.1 to 96.5)
Test 3 vs 2		14.8 (6.3) (95% CI 0.6 to 28.9)		12.8 (4.9) (95% CI 1.9 to 23.6)

HR = heart rate; BS = breathlessness; PE = perceived exertion.
↵6-150 Signficantly different from tests 2 and 3 (p<0.05).
↵6-151 Mean (SD) values for three 85% ESWTs performed over a 15 day period.
↵6-152 Mean (SE) and 95% confidence intervals for the differences between repeat tests.
