Incidence of pelvic inflammatory disease in untreated women infected with Chlamydia trachomatis

摘要

Risser and Risser's interesting review shows that the evidence on the incidence of pelvic inflammatory disease (PID) in untreated chlamydia infected women is unclear.1 They highlight numerous methodological issues concerned with the ability to infer an estimation of the incidence of PID following chlamydia infection, including small sample size, short duration of follow-up period and lack of adequate knowledge of the natural history of chlamydia.
