The HRs in the univariate analyses are higher for all cardiovascular disease items compared to the method of using SST in the model.
Four outcome variables were identified based on chronic disease items from the WHS.
Social support, effect of kidney disease, and burden of kidney disease items exhibited a stronger relationship (>0.7).
SLAM may also have some difficulty in distinguishing a change, in particular when scoring minimally active disease items versus damage.
Several items were pooled to create combined variables, including a general circulatory disease deficit that contained congestive heart failure, irregularly irregular pulse and peripheral vascular disease items.
Indeed, it has been convincingly shown that the prevalence of multimorbity increases as the number of disease items included in the questionnaire increases [ 34, 35].
In patients with established cardiovascular disease (items: myocardial infarction/acute coronary syndrome, stroke/TIA, PAD if questionnaire indicated to be present) or type-2-diabetes mellitus thresholds of < 175 for TC and < 100 mg/dl for LDL-C were applied.
The ADKS is conceptually split into the following seven content domains: life impact (items 1, 11 and 28), risk factors (items 2, 13, 18, 25, 26 and 27), symptoms (items 19, 22, 23 and 30), treatment and management (items 9, 12, 24 and 29), assessment and diagnosis (items 4, 10, 20 and 21 ), care giving (items 5, 6, 7, 15 and 16) and course of the disease (items 3, 8, 14 and 17) [ 18].
Although a pilot evaluation of the quality of reporting was carried out among all reviewers, no additional criteria were defined for specification of the severity of all diseases (item 18) described in the studies.
The survey instrument consisted of 75 items and was divided into five domains: demographic data (10 items), cognition of COPD (15 items), behaviors (5 items), disease management (10 items), qualities of life (25 items) and economic burdens (10 items).
