Table 2 |. Correlations of demographic variables with placental dysfunction.

For all correlations, the total number of participants is 24. The parameters are summarized as median (IQR) within each group except for nulliparity, which is presented as a percentage. The p-values were obtained using a two-sided Wilcoxon rank sum test except for nulliparity, for which they were obtained using a two-sided Fisher’s exact test.
