Characteristics of 997 Cardiovascular Health Study All Stars Study participants at the baseline (2005–2006) examination
| Meana | sda | n (%) | |
|---|---|---|---|
| Age (yr) | 85.2 | 3.6 | |
| Male | 362 (36%) | ||
| Black race | 163 (16%) | ||
| Body mass index (kg/m2) | 26.7 | 4.6 | |
| Serum creatinine (mg/dl) | 1.1 | 0.5 | |
| C-reactive protein (mg/liter)a | 2.0 | 4.6 | |
| Serum albumin (mg/dl) | 3.8 | 0.3 | |
| Diabetes | 161 (16%) | ||
| IGF-I (μg/liter) | 152.7 | 60.9 | |
| IGFBP-1 (μg/liter) | 54.4 | 37.0 | |
| IGFBP-3 (μg/liter) | 3075.0 | 912.4 |
For each variable, fewer than 5% of subjects had missing values. Data were missing for 11 subjects for IGF-I and two subjects for IGFBP-3. Conversion factors to change published units to SI units are: creatinine, mg/dl × 88.4 = μmol/liter; C-reactive protein, mg/liter × 9.524 = nmol/liter; IGF-I, μg/liter × 0.131 = nmol/liter; IGFBP-1, μg/liter × 0.22 = nmol/liter; and IGFBP-3, μg/liter × 0.035 = nmol/liter.

Values shown for C-reactive protein are the median and 75th percentile.
