[Retracted] Association between the Predicted Value of APACHE IV Scores and Intensive Care Unit Mortality: A Secondary Analysis Based on EICU Dataset

Table 1

Threshold saturation effect.

Outcome	Death in EICU ward
The model I
Linear effect	1.03 (1.02, 1.05) 0.0002
The model II
Fold point (K)	70
<K segment effect 1	1.00 (0.96, 1.04) 0.9925
>K segment effect 2	1.05 (1.02, 1.08) 0.0003
The effect of 2 is not equal to 1	1.05 (0.99, 1.11) 0.0915
Predicted value of the equation at the break point	-3.80 (-4.81, -2.79)

Data in table: (95% CI) value/OR (95% CI) value. Outcome variables: death in ICU ward; exposure variables: acute physiology score (IV); adjust the variable: none.
