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
ObjectiveThis study aimed to assess the prevalence of anemia in Hungary between 2019 and 2022 as detailed data in this regard was not available.MethodsThis retrospective, observational, cross-sectional study enrolled 85628 patients with a median age of 63 (44-76 interquartile range) years admitted to the Emergency Department of the University of Pécs, Hungary, between January, 2019, and December, 2022.ResultsThe overall prevalence of anemia was 22.68%. The prevalence of anemia did not change significantly during the study period (2019: 22.30%; 2020: 22.88%; 2021: 22.55%; 2022: 23.00%). However, the prevalence of severe anemia (Hgb<8g/dL) was higher compared to 2019, in each year (2019:2.00%; 2020:2.52%; 2021:2.60%; 2022:2.47%, p<0.001). The increase was observed in each analyzed year among the elderly male patients and in 2021 and 2022 among the elderly female patients. The rising number of patients with COVID-19 diagnosis presenting severe anemia may have contributed to this change. Among all anemic patients, the overall prevalence of microcytic and macrocytic anemia accounted for one-third, while hypochromic and hyperchromic anemia for half of the cases. Hypochromic anemia prevalence decreased and normochromic anemia prevalence increased significantly in each year. The prevalence of microcytic anemia decreased in the year 2020 compared to 2019, the changes being observed among the female patients only.ConclusionsOver the study period, anemia affected approximately one-quarter of the patients each year, while the proportion of severe anemia increased, especially in the elderly.
