What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPersistent infection with high-risk human papillomavirus (HPV) types is necessary for the development of high-grade cervical dysplasia and cervical carcinoma. The presence of HPV DNA in the blood of cervical cancer patients has been reported; however, whether HPV DNA is detectable in the blood of patients with pre-invasive cervical disease is unclear.
objectivesThe objectives of this study were to determine if HPV 16 and HPV 18 DNA could be detected in the serum of colposcopy clinic patients, and if serum HPV detection was associated with grade of cervical disease and HPV cofactors. STUDY
designSamples were selected from a biorepository collected from non-pregnant, HIV-negative women ages 18-69 attending colposcopy clinics at two urban public hospitals. Cervical disease status was based on review of colposcopy, biopsy and cytology findings. Serum HPV DNA detection was conducted using a novel PCR and mass spectroscopy-based assay.
resultsOf the 116 adequate serum samples, all (100%) were negative for HPV 16 and HPV 18. Over half (51.7%) of participants had cervical HPV 16 and/or HPV 18 infection. Nearly one-third (31.1%) had high grade, 10.3% had low grade, and 50.9% had no cervical disease. Nearly one-third (28.5%) had ever regularly smoked cigarettes, 70.7% had early onset of sexual intercourse, and 75% had ever used oral contraceptives.
conclusionsIn this colposcopy clinic population with a range of clinical characteristics and established HPV cofactors, HPV DNA was undetectable in their serum. Our findings suggest that serum HPV DNA detection is not a cervical cancer screening tool.
