Meta Analysis
Human papillomavirus type-distribution in condylomata acuminata of mainland China: a meta-analysis.
The aim of this work was to study the human papillomavirus (HPV) type-distribution in condylomata acuminata (CA) of mainland China and to estimate the potential role of HPV prophylactic vaccines for CA in mainland China. Forty-three studies using polymerase chain reaction to detect HPV were included in this meta-analysis, and totally 5247 CA cases and 436 controls were included. The overall and type-specific prevalence of HPV 6, 11, 40, 42, 43, 44 were estimated using non-conditional logistic regression model. ⋯ Estimated HPV types 6, 11, 40, 42 positive fractions in CA were 54.9%, 41.1%, 2.7% and 2.0%, respectively, and exactly 0% for HPV types 43 and 44. HPV 6 and/or 11-positive fractions were 83.0% in mainland China. Thus, prophylactic HPV vaccine has the potential to protect up to 83% of CA cases in mainland China.
