Test-retest submission of the Walking Estimated Limitation Calculated by History (WELCH) in revascularized (filled squares) and nonrevascularized (open circles) patients. Score 1 and score 2 are the results observed during the first and second questionnaire submission, respectively. The regression line (with its equation) is for nonrevascularized patients only to estimate test-retest reliability.
