Human papillomavirus type 16 (HPV-16) IgG antibody among women of reproductive age presenting at a healthcare facility in Central Nigeria: a pilot study.

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
Approximately, 70% of cervical cancer cases worldwide are attributable to HPV-16 and HPV-18, with HPV-associated cancers being the second most common infection-related cancers globally. However, there´s paucity of data about this infective agent in Central Nigeria. In a cross-sectional study, we evaluated the seroprevalence of HPV-16 immunoglobulin G (IgG) and risk determinants among women in Central Nigeria as a first step towards evaluating anti-HPV IgM antibody for active cases and determining incidence. Blood samples were collected between August 2016 and January 2018, from 400 consenting women of childbearing age (15-49 years) who completed structured questionnaires. Samples were analyzed using HPV-16 specific IgG ELISA kits (Cusabio Co. Ltd, Germany). Statistical analysis was performed to determine predictors. Overall, we found that 128 (32.0%) had IgG antibody against HPV-16. Seroprevalence by age was 50.0% (15-19 years), 55.0% (20-24 years), 12.9% (25-29 years), 50.0% (30-34 years), 32.1% (35-39 years), 18.2% (40-44 years) and 19.4% (45-49 years) respectively. Factors associated with infection were age (P=0.0002; 95% CI 5.06-31.51), occupation (P<0.0001; 95% CI 1.4-12.6), number of sex partners (P=0.0037; 95% CI 1.27-49.93), history of genital warts (P=0.0203; 95% CI 1.34-9.55) and education level (P<0.0001; 95% CI 3.89-60.11). In addition, forty six (11.5%) reported having the history of genital warts with 268 (67.0%) and 132 (33.0%) subjects being married and single respectively. Individuals who were either artisans or civil servants were 260 (65.0%), whereas 140 (35.0%) were students. Majority, 324 (81.0%), had either primary, secondary or tertiary education with 76 (19.0%) of the subjects having no formal education. In respect of sexual behaviour, 196 (49.0%) reported having at least two sexual partners, out of which 64 (16.0%) had three or more. These findings provide high serological evidence of exposure to HPV-16 in Central Nigeria with implications for national and regional intervention initiatives.
