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.
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
backgroundHuman Parvovirus B19 is a common human pathogen that causes fifth disease that can be severe for immunocompromised people and unborn children. Blood donations are routinely screened for the presence of Parvovirus B19 DNA to release plasma for the fractionation industry. MATERIALS AND
methodsVoluntary, unremunerated blood donations from six regions of Switzerland were tested by Interregional Blood Transfusion Swiss Red Cross since 2008. Individual blood donations with viral titers exceeding 10
resultsFrom 2008 until September 2024, 2,789,113 blood donations were tested for the presence of Parvovirus B19 DNA, of which 271 were considered positive. Two small outbreaks in the years 2013 and 2017 and an unprecedented massive outbreak in winter/spring 2023/2024 were detected. The incidence in the 2023/2024 outbreak was 15.1 per 10,000 donations and thus about ten times higher than in the previous outbreaks with 1.6 and 1.2 positive cases per 10,000 donations, respectively. Of the genotyped cases from the 2023/2024 outbreak all were caused by Parvovirus B19 of genotype 1a2. Viral titers reached maximum values of 3×10 DISCUSSION: Similar to the situation in other European countries, Switzerland was struck with an unprecedented Parvovirus B19 outbreak in 2023/2024. The outbreak follows a two-year stretch with no positive Parvovirus B19 cases. It is likely that the measures implemented in 2020 to confine the spread of SARS-CoV-2 had a strong impact on other infectious diseases like Parvovirus B19.
