^*Responses to the Walking Impairment Questionnaire were scored on a 0–4 scale, where 4 represented greatest limitation and 0 represented least limitation. Values are expressed as means (SD). P values derived from tests for trend across GDS-S categories (0–1, 2–3, 4–5, and 6+). Data on pain, aching, or cramps in calves/buttocks were missing for 1 patient, and data on pain or aching in thighs were missing for 1 patient.
