Variation in transcription values for three selected transcripts depending on gestational age.

<p>Transcription values (normalised) are plotted for different gestational ages (weeks). The red points represent preeclamptic (PE) pregnancies and blue points normal pregnancies (NP). The lines are the estimated regression lines for gestational age (red line for PE, blue line for NP), separated by the regression coefficient for PE-status. In Figure A, the transcription level is significantly associated with both PE-status and gestational age. In B, the transcription level is associated with gestational age only, and in C with PE-status only.
