Sensitivity Analysis of MES and MRIPH Presence/Absence—Goodness of Fit
| Risk Factor | Full Model: Hazard Ratios (95% CI) | Model Without MES: Hazard Ratios (95% CI) | Model Without MRIPH: Hazard Ratios (95% CI) |
|---|---|---|---|
| Sex (female) | 2.39 (0.95 to 6.01) | 2.25 (0.88 to 5.77) | 1.18 (0.52 to 2.70) |
| Smoking (present) | 3.17 (1.32 to 7.62)* | 3.37 (1.38 to 8.25)* | 2.21 (1.01 to 4.83)* |
| MES presence | 2.91 (1.45 to 5.84)* | — | 3.36 (1.69 to 6.67)* |
| MRIPH presence | 10.98 (3.12 to 38.64)* | 12.67 (3.55 to 45.28)* | — |
| Goodness of fit (AIC) | 268.80 | 276.12 | 290.25 |
AIC indicates Akaike information criterion; CI, confidence interval; MES, microembolic signals; MRIPH, plaque haemorrhage detected by magnetic resonance imaging.
