Sentence |
denotes |
Regularized logistic regression led to the selection of the variables age, cardiovascular disease and hypertension with respect to the prediction of arrhythmia incidence. |
| T155 |
171-514 |
Sentence |
denotes |
The subsequently fitted multiple logistic regression model revealed significant association of age (OR 1.036; 95% CI 1.004–1.074; p = 0.036) and cardiovascular disease (OR 3.307; 95% CI 1.329–8.232; p = 0.01) with incident arrhythmia in COVID-19, whereas the effect of hypertension was not significant (OR 2.08; 95% CI 0.794–5.796; p = 0.144). |

| T158 |
695-857 |
Sentence |
denotes |
Left ventricular ejection fraction was documented in 47.1% of patients with incident arrhythmia and only 21.2% of cases without arrhythmia during hospitalization. |
| T159 |
858-1055 |
Sentence |
denotes |
Attempts at imputing LVEF and including the imputed dataset in the final logistic regression model hinted at a potential role of LVEF as an additional predictor for arrhythmia incidence (Table S1). |
| T160 |
1056-1211 |
Sentence |
denotes |
However, due to the high number of missing values, LVEF was omitted from the final logistic regression model to ensure reliability of statistical analyses. |
