SARS-CoV-2 viral dynamics of the first 1000 sequences from Vietnam and neighbouring ASEAN countries.
Article in IJID regions, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Objective: The regional distribution and transmissibility of existing COVID-19 variants of concern (VOC) has led to concerns about increasing transmission, given the ability of VOCs to evade immunity as breakthrough infections become more prevalent. Methods: SARS-CoV-2 genomes ( Results: Between January and November 8, 2021, VOCs, including alpha (B.1.1.7), beta (B.1.351), gamma (P.1), and delta (B.1.617.2), were observed across the ASEAN countries. While alpha and delta were the major VOCs in nine ASEAN countries, delta was predominant. The alpha VOC was first reported by Singapore, beta by Malaysia, gamma by the Philippines, and delta by Singapore. Of the first 1000 genomes analysed from Vietnam, alpha and delta were the most represented, with delta being the dominant VOC from May 2021. The delta variant was introduced in early January 2021, and formed a large cluster within the representative genomes. Conclusion: Spatial and temporal monitoring of SARS-CoV-2 variants is critical to the understanding of viral phylodynamics, and will provide useful guidance to policy makers for infection prevention and control.
