Adjusted Means of the Short Physical Performance Battery Score According to the ABI in the Entire Cohort and in Participants Without Exertional Leg Symptoms*
| Definite PAD (ABI <0.90), Mean (95% Confidence Interval) | Borderline PAD (ABI 0.90 to 0.99), Mean (95% Confidence Interval) | Low Normal ABI (ABI 1.00 to 1.09), Mean (95% Confidence Interval) | No PAD (ABI 1.10 to 1.40), Mean (95% Confidence Interval) | P Value | |
|---|---|---|---|---|---|
| Entire Cohort | N=220 | N=250 | N=509 | N=587 | |
| SPPB score (0 to 12 scale, 12=best) | 7.34 (7.13 to 7.57) | 7.45 (7.25 to 7.66) | 7.36 (7.22 to 7.51) | 7.40 (7.26 to 7.53) | 0.87 |
| Participants Without Exertional Leg Symptoms | N=144 | N=191 | N=388 | N=437 | |
| SPPB score (0 to 12 scale, 12=best) | 7.22 (6.95 to 7.50) | 7.46 (7.22 to 7.69) | 7.38 (7.22 to 7.55) | 7.40 (7.24 to 7.56) | 0.60 |
ABI indicates ankle brachial index; BMI, body mass index; PAD, peripheral artery disease; SPPB, short physical performance battery.
