Vascular disease burden is computed using self-report questions for the following 3 items*:
Each item is given a value of 0 or 1 (see response options below). The cumulative score for vascular disease burden ranges from 0 to 3 and is the mean of the 3 individual scores multiplied by 3. Higher scores indicate greater vascular disease burden. The score for vascular disease burden is calculated if at least 2/3 of the questions are answered.
*In addition to self-report, evaluation of stroke is also based on neurological exam (when available), cognitive testing, and interview of participant, with which the physician may render a diagnosis of stroke.
Response values for each item:
|0||Never reported pain in legs or any reported pain that did not include the calves, from baseline to this cycle|
|1||Reported pain in legs while walking which includes calves, in at least one cycle from baseline to this cycle|
|0||Stroke not present (Possible stroke dx or stroke not present), in all cycles, from baseline to this cycle|
|1||Stroke present (Highly probable or probable stroke dx) reported in at least one cycle from baseline to this cycle|
|0||Never reported in past history or in follow-up cycle up to this cycle (includes suspect or possible)|
|1||Reported in past history or in at least 1 follow-up cycle up to this cycle|
Note: A 4-item version of this variable includes CHF questions and is available for MAP/MARS only.
