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

Previous findings of hepatitis C virus (HCV) in human semen have been inconsistent. This study attempted to elucidate the presence of HCV in semen from 80 HCV RNA blood plasma positive homeless men using two novel non-PCR based techniques. Semen was frozen immediately upon ejaculation in order to preserve virus quantity. This study demonstrated that 36% of the study population had HCV in semen. Bayer's Versant HCV RNA Qualitative Assay (Bayer Diagnostics, Emeryville, CA) based on transcription mediated amplification (TMA) assay detected 29 positive semen samples and Versant HCV RNA 3.0 Assay (bDNA) (Bayer Diagnostics, Emeryville, CA) detected only six. This demonstrated that TMA was more sensitive than the bDNA in detecting HCV in semen (P<0.002). HCV blood plasma viral load was positively correlated with the presence of HCV in semen (Spearman's Rho=0.40, P<0.0002), while the presence of leukocytes in semen was not (Spearman's Rho=0.19, P<0.12). This supports the hypothesis that HCV is "leaked out" from the peripheral circulation into semen. Three semen samples had a viral load of >5000 IU/mL. The presence of a high viral load in semen in certain men suggests that sexual transmission of the virus is possible. Laboratory capability to accurately detect HCV positive semen is an important step in establishing the risk of sexual transmission and in identifying strategies for protecting uninfected partners.
