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

backgroundAn ecological correlation between invasive cervical cancer incidence and burden of soil-transmitted helminths (STH) is hypothesized to explain the excess in detectable human papillomavirus (HPV) infection in Latin America, via a global T-helper type 2 (Th2)-biased mucosal immune response secondary to STH infection.

methodsThe association between current STH infection and HPV prevalence was compared in regions of Peru where STH is or is not endemic. Adjusted prevalence ratios (PRs) with robust variance were estimated as an effect measure of STH infection on HPV prevalence in each study site. Soluble immune marker profiles in STH-infected and STH-uninfected women were compared using Spearman rank correlation with the Sidak correction.

resultsAmong women in the helminth-endemic region of the Peruvian Amazon, those with STH infection women had a 60% higher prevalence of HPV, compared with those without STH infection (PR, 1.6; 95% confidence interval, 1.0-2.7). Non-STH parasitic/protozoal infections in the non-STH-endemic population of Peru were not associated with HPV prevalence. In Iquitos, A Th2 immune profile was observed in cervical fluid from helminth-infected women but not helminth-uninfected women.

conclusionsA proportion of the increased HPV prevalence at older ages observed in Latin America may be due to a population-level difference in the efficiency of immunological control of HPV across the lifespan due to endemic STH infection.
