1 · What the graph read from it

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.

2 · The registry

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

BACKGROUND/

objectiveCervical Cancer is the 6th most common and 3rd most deadly cancer among women. Despite the fact that the majority of the countries in Asia and Africa have a similar economy and low life expectancy, the mean age-standardized incidence rate (ASIR) of cervical cancer is substantially higher in Africa than in Asia. This study identified the correlates of the higher ASIR rates in Africa relative to Asia against two timelines; 2004-2009 and 2010-2017.

methodsPeer-reviewed articles published between 2004 and 2017 were selected using the PRISMA standard. Sources of articles included Google Scholar, Scopus, PubMed Central, and EMBASE. Search keywords included: HPV genotypes, cervical cancer, HPV vaccine, and multiple infections in Africa and Asia.

resultTwenty-nine and seventeen full-length articles were selected from Africa and Asia, respectively. The pooled prevalence of HPV infection up to 2017 was higher in Africa (41.8%; 95% CI: 35.9, 47.7) than in Asia (24.2%; 95% CI: 16.22, 32.2) at p< 0.001. Between 2004-2009 and 2010-2017 timelines, the pooled prevalence of HPV infection decreased from 49.1% to 36.7% (OR': 1.66, 95% CI: 1.51-1.80) in Africa and increased from 16.9% to 20.5% (OR': 0.79, 95% CI: 0.71-0.86) in Asia. However, the pooled prevalence of multiple HPV infections and non-vaccine high-risk HPV infections were higher among African women diagnosed with cancer (30.9% and 5.2%) than their Asian counterparts (21.0% and 2.0%, respectively) at p< 0.001. Additionally, the pooled prevalence of the five most prevalent high-risk HPV types in Africa were HPV16 (35.3%), HPV52 (14.2%), HPV35 (12.4%), HPV18 (10.4%), and HPV58 (10.0%), while that of Asia were HPV16 (37.3%), HPV52 (16.2%), HPV58 (14.7%), HPV33 (7.4%) and HPV18 (7.2%).

conclusionThis study suggests that the higher prevalence of HPV, multiple HPV and non-vaccine HPV infections could be responsible for the higher ASIR in Africa than in Asia.
