Homo sapiens
Body site Anatomical site where microbial samples were extracted from according to the Uber Anatomy Ontology
Uterus Uterus,uterus
Condition The experimental condition / phenotype studied according to the Experimental Factor Ontology
Human papilloma virus infection HPV,Human Papilloma Virus Infection,Human papilloma Virus infection,human papilloma virus infection,Human papillomavirus caused disease or disorder,Human papillomavirus disease or disorder,Human Papillomavirus Infection,Human Papillomavirus infection,Human papillomavirus infectious disease,Human papilloma virus infection
Group 0 name Corresponds to the control (unexposed) group for case-control studies
HPV presistent and negative
Group 1 name Corresponds to the case (exposed) group for case-control studies
HPV clearance
Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
HPV DNA was detected using the Digene HC2 high-risk DNA test (Qiagen, Gaithersburg, MD, USA) with signal amplification and chemiluminescence for 13 types of HR-HPV scored in RLU/PC. A positive result indicated a concentration of 1 pg/ml or higher than the RLU/cutoff ratio (RLU of the specimen/mean RLU of 2 positive controls).
Group 0 sample size Number of subjects in the control (unexposed) group
26
Group 1 sample size Number of subjects in the case (exposed) group
