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

objectiveTo characterize hepatitis C virus (HCV) epidemiology in countries of the Fertile Crescent region of the Middle East and North Africa (MENA), namely Iraq, Jordan, Lebanon, Palestine, and Syria.

methodsWe systematically reviewed and synthesized available records of HCV incidence and prevalence following PRISMA guidelines. Meta-analyses were implemented using a DerSimonian-Laird random effects model with inverse weighting to estimate the country-specific HCV prevalence among the various at risk population groups.

resultsWe identified eight HCV incidence and 240 HCV prevalence measures in the Fertile Crescent. HCV sero-conversion risk among hemodialysis patients was 9.2% in Jordan and 40.3% in Iraq, and ranged between 0% and 3.5% among other populations in Iraq over different follow-up times. Our meta-analyses estimated HCV prevalence among the general population at 0.2% in Iraq (range: 0-7.2%; 95% CI: 0.1-0.3%), 0.3% in Jordan (range: 0-2.0%; 95% CI: 0.1-0.5%), 0.2% in Lebanon (range: 0-3.4%; 95% CI: 0.1-0.3%), 0.2% in Palestine (range: 0-9.0%; 95% CI: 0.2-0.3%), and 0.4% in Syria (range: 0.3-0.9%; 95% CI: 0.4-0.5%). Among populations at high risk, HCV prevalence was estimated at 19.5% in Iraq (range: 0-67.3%; 95% CI: 14.9-24.5%), 37.0% in Jordan (range: 21-59.5%; 95% CI: 29.3-45.0%), 14.5% in Lebanon (range: 0-52.8%; 95% CI: 5.6-26.5%), and 47.4% in Syria (range: 21.0-75.0%; 95% CI: 32.5-62.5%). Genotypes 4 and 1 appear to be the dominant circulating strains.

conclusionsHCV prevalence in the population at large appears to be below 1%, lower than that in other MENA sub-regions, and tending towards the lower end of the global range. However, there is evidence for ongoing HCV transmission within medical facilities and among people who inject drugs (PWID). Migration dynamics appear to have played a role in determining the circulating genotypes. HCV prevention efforts should be targeted, and focus on infection control in clinical settings and harm reduction among PWID.
