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

backgroundSeasonal influenza virus infections remain a major public health burden. During the last years, several case reports of severe influenza infections in children have been published. CASES: We report 4 fatal influenza cases in young children (2-6 years old) which occurred in Southwest Germany in the seasons 2022/23 and 2023/24. All 4 children were previously healthy; a forensic autopsy was conducted due to an unknown cause of death. Postmortem samples from the respiratory tract and organ tissues were tested for respiratory viruses via real-time polymerase chain reaction (RT-PCR) and analyzed by whole-genome sequencing.

resultsIn 1 child, RT-PCR revealed influenza B virus, and 3 children died with influenza A (H1N1)pdm09 infection. No mutations associated with high virulence were detected. In 1 case, influenza A(H1N1)pdm09 could be cultivated in cell culture from brain tissue.

conclusionsThis case series underlines the potential risk of fatal outcomes of influenza infections in children. This should be considered when re-evaluating the vaccination recommendations for healthy children.
