The boxplots below compare various chemokines in amniotic fluid (GRO-?, interleukin-8, and L-selectin) in patients with (IAI) and without intra-amniotic infection (non-IAI).

Amniocentesis was performed on 45 pregnant women with preterm contractions, labor, or rupture of membranes. Fourteen patients had intra-amniotic infection, and 31 did not.
