- •
We report nonlinear analysis of asymptomatic partial placental abruption (aPPA).
- •
The values of nonlinear indices (ApEn, SampEn, and CD) are notably lower with aPPA.
- •
Negative correlation between the degree of aPPA and nonlinear indices is observed.
- •
Nonlinear analysis is a valuable tool to quantitatively assess subclinical conditions.
