Fig. 2: The response of different infectious indicators to dexamethasone
in PPROM women
A and B: WBC and neutrophil increased 24 hours after the first injection
in both groups, followed by a decrease at 72 hours post first injection
to levels that remained higher than the baseline. No significance was
found between two groups. C: Mean lymphocyte declined at 24 hours
whereas peaked ultimately at 72 hours. There was no significance between
the two groups. D and E: In the HCA groups, CRP temporarily increased at
24 hours before dropping to the baseline and remaining at stable level;
PCT increased continually to
the peak at 72 hours. Both CRP and PCT were significantly higher in HCA
group after first injection.
Fig. 3: The ROC curves of CRP and PCT for HCA after administration of
dexamethasone
A: For women at baseline, the area under ROC curve of PCT was
significantly better than that of CRP (0.763 vs. 0.588;
p<0.05). B: The areas under ROC curve of CRP and PCT were
0.788 and 0.730, respectively. No significance was found between them.
C: The area under ROC curve of PCT was significantly better than that of
CRP at 48 hours (0.901 vs. 0.701; p<0.05). D: The area under
ROC curve of PCT was significantly better than that of CRP at 48 hours
(0.902 vs. 0.714; p<0.05).
