The Role of Chlamydia trachomatis Polymorphic Membrane Proteins in Inflammation and Sequelae among Women with Pelvic Inflammatory Disease

Table 5

Effect of Pmp antibody reactivity on time-to-pregnancy and time-to-recurrent PID.

Subgroup	Pregnancy		Recurrent PID
	Crude HR (95% CI)	^aAdjusted HR (95% CI)	Crude HR (95% CI)	^aAdjusted HR (95% CI)
^bHigh PmpD (𝑛=28)	0.7 (0.3–1.3)	0.7 (0.3–1.6)	0.9 (0.2–4.7)	1.3 (0.2–8.3)
^cHigh PmpI (𝑛=23)	1.3 (0.7–2.7)	1.4 (0.7–3.0)	0.6 (0.1–3.0)	0.7 (0.1–5.3)

^aModels were adjusted for age, race, and models predicting infertility, pregnancy, and live birth were additionally adjusted for infertility self-reported at baseline; ^bPmpD antibody reactivity is based on a median cut-point; low reactivity <0.41, high reactivity ≥0.41; ^cPmpI antibody reactivity is based on a median cut-point; low reactivity <0.89, high reactivity ≥0.89.
