Exploring Evolutionary Constraints in the Proteomes of Zika, Dengue, and Other Flaviviruses to Find Fitness-Critical Sites.
Article in Journal of molecular evolution, 2020. 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
Dengue virus (DENV) challenges vaccine design due to antibody-dependent enhancement (ADE) and evidence suggests that Zika virus (ZIKV) experiences ADE with DENV and West Nile virus (WNV) antibodies. Thus, multiple flaviviruses must be considered when developing novel therapies against ZIKV. We analyzed 42 flavivirus polyproteins in their evolutionary context to identify motifs conserved in sequence with low real-time and evolutionary conformational flexibility, thought to be fitness-critical sites. We also analyzed evolutionary rate-shifts between clades for insight on vector specificity. For mosquito-borne flaviviruses, two conserved motifs were identified within the RNA-dependent RNA polymerase (RdRP), critical for flavivirus genome replication. Clade-specific motifs were identified for the ZIKV+DENV and WNV clades, many of which were also in RdRP. Six sites in motifs for WNV experienced significant evolutionary rate-shifts, suggesting their importance for functional divergence. Overall, some of these motifs are prime candidates as broadly neutralizing antiviral drug targets across different mosquito-borne flaviviruses.
