Anogenital HPV genotypes are classified into high-risk, low-risk, and intermediate-risk groups based on oncogenic potential, with specific genotypes in each group.
“HPV16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 68, 73 and 82 are included in high-risk group while HPV6, 11, 40, 42, 43, 44, 54, 61, 70, 72 and 81 are included in low-risk group whereas HPV 26, 53 and 66 belong to the group of intermediate risk [2, 3].”
From HPV Genotypes distribution in Indian women with and without cervical carcinoma: Implication for HPV vaccination program in Odisha, Eastern India (2017) · cites this paper as [3]
The section “Classification of weakly carcinogenic human papillomavirus types” (page unavailable) says HPV types vary in carcinogenic potential and identifies HPV16 and HPV18 as powerful carcinogens. The available copy does not substantiate the sentence’s remaining genotype lists or its specific high-, low-, and intermediate-risk assignments. (LLM, conf=0.82)
Experimental — accuracy not yet measuredThe 12 Group 1 carcinogenic HPV types have been grouped according to their prevalence in cervical cancer into Groups 1a, 1b, 1c, and 1d.
“The 12 Group 1 carcinogenic HPV types have been recently grouped according to their prevalence in cervical cancer, which is a marker of their carcinogenicity, into Groups 1a (HPV 16: most carcinogenic), 1b (HPV types 18 and 45), 1c (HPV types 31,33,35,52,58) and 1d (39,51,56,59 - least carcinogenic).37 38”
From Protocol for a cervical screening implementation trial comparing two approaches for delivering HPV self-collection in low-resource settings in India: a type 3 hybrid cluster randomised controlled trial (SHE-CAN) (2025) · cites this paper as [37]
The section “Classification of weakly carcinogenic human papillomavirus types” says HPV types differ in carcinogenic potential and identifies HPV 16 and 18 as powerful carcinogens, but it does not give the claimed 12-type classification into Groups 1a–1d. Searches for those group labels and for classification by prevalence in cervical cancer found no supporting passage in our truncated copy. (LLM, conf=0.72)
Experimental — accuracy not yet measuredAmong 184 different HPV genotypes, only 40 diverse types can infect the anogenital region.
“Among 184 different HPV genotypes, only 40 diverse types can infect anogenital region which can be classified into 3 classes based on their oncogenic potential.”
From HPV Genotypes distribution in Indian women with and without cervical carcinoma: Implication for HPV vaccination program in Odisha, Eastern India (2017) · cites this paper as [3]
The 'Historical aspects' passage links HPV types to anogenital cancers and mentions 120 fully sequenced genotypes, but it does not give the claimed total of 184 or say that 40 types can infect the anogenital region. Searches for those numbers and for anogenital HPV types found no decisive passage; the copy is truncated, so the relevant text may be missing. (LLM, conf=0.70)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
