Parity emerges as the strongest predictor, showing a significant negative association with PAPP-A levels ( p = 0.026), while its effect on NT is weaker and only borderline significant ( p = 0.079).
Parity emerges as the strongest predictor, showing a significant negative association with PAPP-A levels ( p = 0.026), while its effect on NT is weaker and only borderline significant ( p = 0.079).
With 105 valid cases analyzed, this finding suggests a possible trend but lacks sufficient statistical evidence to confirm a strong or reliable association.
Parity showed a moderate negative trend (B = −0.250; p = 0.079), nearing significance but not conclusive.
Non-smokers showed a trend toward lower risk of low PAPP-A, although the association was not statistically significant.
