Median expression levels of interferon signaling genes among women with PID and
chronic endometritis due to CT+GC, GC only, and CT only; and women
without PID or endometritis with cervical infection due to CT or CT+GC,
and asymptomatic uninfected women. Dots represent the median expression value
for each individual transcript (log2 transformed expression) in all five subject
groups in interferon modules (M1.2, M3.4, and M5.12) while the black bar
indicates the group mean. Pairwise comparisons followed significant ANOVA after
Bonferroni correction for all three modules. Genes related to interferon were
significantly overexpressed in women with PID and chronic endometritis induced
by CT alone compared to women with cervical infection due to GC or
CT+GC; (p < 0.001 for M1.2, p
= 0.004 for M3.4, p = 0.045 for M5.12); whereas
expression levels for women with PID and chronic endometritis due to
CT+GC or GC alone were not different than infected cases or uninfected
controls. *, p < 0.05; **,
p < 0.01; ***,
p < 0.001.
