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

backgroundHepatitis E virus (HEV) is prevalent and causes disease worldwide, but its epidemiological profile is only partially understood.

methodsWe used an enzyme immunoassay to measure anti-HEV immunoglobulin G antibodies in 18,695 serum samples collected in the Third National Health and Nutrition Examination Survey. We calculated estimates of HEV seroprevalence and examined associations with putative risk factors.

resultsThe seroprevalence of HEV in the civilian noninstitutionalized United States (US) population during the period from 1988 through 1994 was 21.0% (95% confidence interval [CI], 19.0%-22.9%). Among US-born individuals, males, non-Hispanic whites, and individuals residing in the Midwest and/or in metropolitan areas had the highest seroprevalence estimates. Having a pet in the home (odds ratio [OR], 1.19 [95% CI, 1.01-1.40]) and consuming liver or other organ meats more than once per month (OR, 1.38 [95% CI, 1.01-1.88]) were significantly associated with increased odds of HEV seropositivity.

conclusionsExposure to HEV is common in the US population, although hepatitis E is rarely reported. Having pets and consuming organ meats may play a role in HEV transmission in the United States, but other mechanisms of transmission may also exist. HEV may be considered a possible etiologic agent of acute and chronic hepatitis in US patients reporting no travel history.
