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 O/ME-SA/Ind-2001 lineage of foot-and-mouth disease virus (FMDV) was introduced into China in 2017, which subsequently caused 19 outbreaks of foot-and-mouth disease (FMD) and emerged in 8 provinces in China between 2017 and 2021. It is the first time for WOAH/national reference laboratory for FMD (LVRI) to comprehensively summarize these 19 outbreaks of O/ME-SA/Ind-2001 for consecutive 5 years. Our study selected and conducted whole viral genome sequencing for 9 representative isolates and the VP1 sequences of the FMDV-positive samples collected between 2017 and 2021. Analyses of these gene sequences showed that all the field strains belonged to O/ME-SA/Ind-2001e. Phylogenetic analysis indicated that these viruses were closely related to those circulating in neighboring countries, and there were at least 3 different FMD viral clades (named cluster 1, cluster 2, and cluster 3) circulating during this period. Also, a gradually decreasing nucleotide identity was observed in newly emerging viruses year by year compared with the first isolate identified in 2017. These results suggest extensive movements and constant and rapid evolvement of the O/ME-SA/Ind-2001e sublineage. Besides, the neutralizing antigenic sites in the structural proteins for these O/ME-SA/Ind-2001e viruses were analyzed to predict the vaccine matching between these strains and the commercial vaccine strain O/BY/CHA/2010. The results showed that the VP1 epitope 135-144, highly associated with neutralizing antibody induction, was variable among these strains. The mutations in this region reflected a potential risk of challenging the current vaccine protection. Therefore, there is an urgent need to reinforce the importance of improved FMD surveillance and monitor the evolution of O/ME-SA/Ind-2001e, which will provide essential information for the FMD control program in China and Asia.
