Linear Regression Analysis (Forward) with SDNN, SDNNindex, and SDANN as Dependent Variables
| SDNN | SDNNindex | SDANN | |
|---|---|---|---|
| log hs‐CRP | –19.2 (–29.2; –9.2)‡ | –8.0 (–12.3; –3.7)‡ | –15.8 (–25.8; –5.8)‡ |
| Current smoking | –17.7 (–26.0; –9.3)‡ | –7.2 (–10.8; –3.7)‡ | –13.4 (–21.1; –5.7)† |
| Use of beta‐blocker | –10.4 (–18.1; –2.7)† | NS | –15.4 (–23.8; –7.1)† |
| Gender | 8.8 (0.7;16.8)* | 4.0 (0.5;7.5)* | NS |
The independent determinants of SDNN, SDNNindex, and SDANN are given.
Data represent effects (ms) with 95% confidence intervals in parentheses.
*P < 0.05; †P < 0.01; ‡P < 0.001; NS = not statistically significant.
Other variables included in the model are: age, left ventricular ejection fraction, a previous myocardial infarction, coronary artery stenosis, and use of ACE‐inhibitor (all NS).
