Maternal WBC counts stratified according to the presence or absence of both MIAC and IAI.

<p>A receiver-operating characteristic curve for the presence of both MIAC and IAI is shown (the area under the curve is 0.70 for the WBC cutoff value of >14.0 × 10⁹/L; <i>p</i> < 0.0001). Abbreviations: WBC, white blood cell count; MIAC, microbial invasion of the amniotic cavity; IAI, intra-amniotic inflammation.</p

Maternal serum WBC counts in the PPROM pregnancies complicated by the presence of MIAC and/or IAI.

<p>The women with both MIAC and IAI have a higher WBC count than the women with IAI alone, MIAC alone, and neither MIAC nor IAI. Abbreviations: WBC, white blood cell count; PPROM, preterm prelabor rupture of membranes; MIAC, microbial invasion of the amniotic cavity; IAI, intra-amniotic inflammation.</p
