Whole-genome characterization of prevalent dengue virus serotype-1 in 2023 dengue outbreak of Xishuangbanna, a border area of Laos, Myanmar, and China.

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
Objectives: From June to November 2023, a severe dengue fever outbreak occurred in Xishuangbanna, China, a border area with Myanmar and Laos. This study aimed to identify the pathogen responsible for this outbreak and analyze the genomic characteristics of epidemic strains, providing reference data for dengue prevention and control. Methods: Serum samples from dengue virus (DENV) NS1-positive patients (July-October 2023) were collected. RNA extraction, serotyping via probe quantitative polymerase chain reaction, and whole-genome amplification using 18 primer pairs followed by sequencing were performed. Base and amino acid mutations were analyzed using DNAMAN. Phylogenetic trees (maximum likelihood for the whole genome and neighbor-joining for the E protein) were constructed using MEGA11. Protein secondary structures were compared via online tools provided by PRABI Lyon-Gerland. Results: Among 1465 samples, 833 were DENV-1 positive, with no other dengue serotype or flavivirus co-infection. Genomic analysis of 10 isolates showed high similarity to the 2023 Guangdong strain (PP540291). Non-structural proteins had higher base mutation rates than structural ones, with NS2 showing the highest (10.92%). Many unique 2013 Yunnan strain mutations were preserved. Phylogenetic trees clustered the epidemic strains with Guangdong and Southeast Asian isolates. NS1 RNA-binding sites remained stable. Conclusions: This study provides valuable insights for dengue control in the China-Myanmar-Laos border areas, as well as for viral pathogenesis research and vaccine development.
