Figure 3. Heat Map for Factors Associated with New-Onset Atrial Fibrillation After Non-Cardiac Surgery.
Factors are coded in shades of red or green showing the direction of effect. Red bars indicates positive association and green bars indicate negative association. Darker shades signify a greater contribution to the global Wald score in the logistic regression model. This implies a stronger relationship with new-onset AF after non-cardiac surgery. Lighter shades imply a lack of relationship or lower odds of new-onset AF after non-cardiac surgery.
