First sequenced cases of Omicron BA.2 sublineage in Ecuador.
Article in Virus research, 2023. 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
The largest wave of infection with SARS-CoV-2 virus in Ecuador was observed in mid-December 2021 and early January 2022, driven by B.1.1.529/BA (Omicron) variant. During the second half of March, an increase in the number of daily cases was observed and coincided with the emergence of the BA.2 variant, which we describe in the present study. The first sequenced five cases of SARS-CoV-2 21L/BA.2 in Ecuador were identified using variant specific genotyping by qPCR and confirmed by whole genome sequencing (WGS). The first sequenced Ecuadorian BA.2 isolate was obtained from a person with international travel history who became symptomatic 3 days after travelling, whereas in the other cases no travel history was recorded.
