Table 3. Ten-year CAC progression by baseline AMD status (No AMD vs. Early/Late AMD).
Baseline CAC = 0 | Incident CAC, n (%) | Age, gender, time between CT scans adjusted OR (95% CI) | Multivariable* adjusted OR (95% CI) |
---|---|---|---|
No AMD (n = 1693) | 761 (45%) | ref | ref |
AMD early (n = 44) | 20 (45%) | 0.70 (0.38, 1.31) | 0.78 (0.41, 1.48) |
AMD late (n = 2) | 1 (50%) | 0.69 (0.04, 11.60) | 0.84 (0.05, 15.01) |
Baseline CAC>0 |
