3.3 | Survival analyses
All significant variables obtained during the cross-sectional analyses (except intake of antiarrhythmics and oral anticoagulants) as well as atrial fibrillation, periodontal conditions (staging, CDC, PESA and PISA) were checked again using Kaplan-Meier survival analyses and Cox regression.
Regarding dental parameters only early tooth loss was significantly associated with the incidence of a new adverse events (HR = 2.25, 95 % CI 1.15-4.41, p = 0.007, Figure 2). There was only a trend for an adverse outcome in dependence of CDC degree (Figure 3, p = 0.514), PESA (Figure 4, p = 0.659), and PISA (Figure 5, p = 0.292) but not significance. Regarding previous internal findings PAD (HR = 3.73, 95 % CI 1.22-11.42, p = 0.013, Figure 6) and previous myocardial infarction (HR=3.97, 95 % CI 1.37-11.52, p = 0.006, Figure 7) remained significant. A clear relationship was shown again between atrial fibrillation and a further event with borderline significance (HR = 2.94, 95 % CI 0.92-9.40, p = 0.056, Figure 8).
