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

Varicella-zoster virus (VZV) is a neurotropic virus that establishes lifelong latency in humans. VZV reactivation is associated with a wide range of symptoms, including herpes zoster (HZ; also known as shingles), and has been implicated in the development of dementia, although to an unknown extent. Here we present a large-scale longitudinal analysis of health records from more than 100 million individuals in the United States that demonstrates a consistent relationship of VZV reactivation with dementia after controlling for nearly 400 measured characteristics (covering demographics, socioeconomic factors, comorbidities, medications, proxies for healthcare-seeking behavior, shifts in clinical guidelines and completeness of records). We found that recurrent HZ was associated with an increased risk of dementia compared to a single HZ episode. Additionally, exposure to HZ vaccines was associated with a reduced risk of dementia compared to the control 23-valent pneumococcal polysaccharide vaccine. Furthermore, the reduced risk of dementia after administration of the live-attenuated zoster vaccine waned over time and was highly correlated with a waning of the vaccine-mediated protection against HZ. The dementia risk reduction at 3 and 5 years postexposure was also stronger in individuals who received multiple as opposed to only one dose of the recombinant HZ vaccine and those at greater risk of HZ. Our findings strongly implicate VZV reactivation as a modifiable risk factor for dementia.
