From Delta to Omicron-Genetic Epidemiology of SARS-CoV-2 (hCoV-19) in Southern Poland.
Article in Pathogens (Basel, Switzerland), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Since severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was first reported in Wuhan, China, in December 2019, it has evolved, leading to variants that differ in their transmissibility, severity of disease, and susceptibility to therapy. Our goal was to describe the dynamics of the emergence of SARS-CoV-2 variants among the population of the southern part of Poland (Silesia) in the period from September 2021 to August 2022. Our results showed that, like in the rest of Poland or in neighboring countries (Czech Republic, Slovakia), Delta was replaced by the Omicron BA.1 variant, isolated for the first time in December 2021, and subsequently Omicron BA.2 and its derivative subvariants acquiring further mutations. Finally, in August 2022, only the BA.5.2.26 subvariant was present in Silesia. However, we noted differences in the dynamics of emergence and spread of some Omicron subvariants compared to the rest of Poland and the neighboring countries, which may be due to differences in population density or import of the virus from other regions.
