Article in Health science reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background and Aims: This study aimed to compare the clinical symptoms of mild COVID-19 and influenza during a period when both diseases circulated in the 2023-2024 influenza season in Japan. Methods: Outpatients diagnosed with COVID-19, influenza A, or influenza B by antigen test kits at 10 medical facilities in Japan were enrolled. Data were collected from a self-reported diary. Results: Data from 347 COVID-19, 392 influenza A, and 103 influenza B patients were analyzed. COVID-19 patients were significantly older than those with influenza A and B ( Conclusion: Mild COVID-19 was associated with longer-lasting symptoms than influenza, particularly in individuals aged ≥ 40 years. These results suggest a greater disease burden of COVID-19, even in outpatients with mild disease, compared with influenza.
