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

backgroundApolipoprotein E is polymorphic in the human population. APOE4 has previously been reported to correlate with symptomatic oral and genital herpes disease.

methodsAPOE was genotyped in 182 subjects with herpes simplex virus (HSV) 2 and in 62 subjects with HSV-1, including 44 subjects with both viral types for a total of 200 adults. HSV shedding was measured by PCR from swab samples obtained daily from mucosa for at least 30 days. Participants also maintained a diary of oral or genital lesions.

resultsThe APOE genotypes observed reflected the US white population and the Hardy-Weinberg equilibrium. Genital and oral HSV shedding was detected on 17.2% and 3.7% of overall days, respectively, whereas genital and oral lesion rates were 10.1% and 2.9%. Using Poisson regression and adjusting for known correlates of HSV shedding, a significant association was not observed between the APOE genotype and genital or oral HSV shedding, or genital HSV lesions. However, the presence of the APOE4 allele was associated with a higher rate of oral herpetic lesions, with a relative risk of 4.64 (95% CI 1.32 to 15.05, p=0.016).

conclusionsVariation at the APOE locus may be associated with clinical manifestations of HSV-1 infection, but does not appear to correlate with herpes simplex viral reactivation in humans.
