Fig 4. Scatter diagram showing the correlation of autophagy markers with gestational age.

(a) The ratio of LC3B/Beclin-1 of stained trophoblast was correlated with gestational age for the four groups separately and (b) comparing all groups in one diagram. There was a significant difference between the four groups (p = 0.024). Analysis based on gestational age showed no significant differences of the ratio between the four groups. Separating values <35 weeks GA and >35 weeks GA revealed lower values in the early-onset preeclampsia and IUGR groups compared to the late-onset preeclampsia and normal term groups.
