Fig. 3

Heatmap illustrating the absolute odds ratio deviation. A positive deviation indicating a favorable effect was represented in blue, while a negative deviation suggesting an unfavorable effect was represented in red. The white fitting curve represents the odds ratio deviation close to zero (the “transition curve”), indicating the transition into the region of insult types. The purple line and the black line represent the odds ratio deviation close to − 0.1 and − 0.2, respectively, indicating a 10% and 20% increase in mortality risk
