COVID-19 treatment of hospital patients worldwide at the onset of the pandemic in 2020: a systematic review.
Synthesis in BMC infectious diseases, 2025. 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
In early 2020, no drug had proven efficacy to treat COVID-19 in-patients. This work aimed to describe COVID-19 treatment for in-patients worldwide until June, 2020. A PubMed search was performed with the terms "retrospective observational study", "hospital", "treatment" and "COVID" to identify English-written studies describing treatments given to adult in-patients before June 30, 2020. The identified reports were analyzed, with data extracted regarding patient characteristics and treatments across continents and countries. Overall, 178 studies involving 181,510 patients in 28 countries were analyzed, including 484 patients from Africa, 36,840 from Asia, 69,088 from Europa and 68,524 from North America. The most prescribed drugs were hydroxychloroquine (64.3%, i.e. 41.9% of all patients), corticosteroids (31.0%, i.e. 21.0%) and lopinavir/ritonavir (30.8%, i.e. 12.0%). Corticosteroids was used worldwide with similar rates in Asia, Europe and North America. Hydroxychloroquine dominated prescriptions in Africa, Europe and North America. Asia exhibited unique features: less frequent hydroxychloroquine use, higher oseltamivir use and exclusive use of umifenovir. In Europe, repurposed drugs prescription was the highest in Spain and Italy. Our study is not an exhaustive review of the literature on COVID-19 treatment of in-patients early in 2020 but is the first one to provide a comprehensive overview of COVID-19 treatment modalities in such a broad range of countries worldwide. Our work reveals high prescription rates but also heterogeneity across continents and countries in the treatment of COVID-19 in-patients worldwide. These findings emphasize the critical role of international collaboration in generating and disseminating reliable information for managing emerging diseases.
