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
Infection with Zika virus (ZIKV) is a perinatal health problem and a vertical infection that promotes neurological fetal damage. ZIKV infects different cellular components at the maternal-fetal interface, including umbilical cord endothelial cells (HUVECs). Extracellular vesicles (EVs) are cellular components that mediate extracellular communication. Viruses have the capacity to hijack and modify the biogenesis machinery of EVs for their own benefit. The present work provides proteomic results (2D electrophoresis) that show the regulation of the expression of proteins involved in autophagy, oxidative stress, and exosome biogenesis in HUVECs infected with ZIKV. We confirmed that Alix and CD9 proteins were downregulated following the infection. Additionally, EVs isolated from infected cells showed the expression of Alix, and CD9 was increased in contrast to the mock condition. Interestingly, nanoparticle tracking and cryo-microscopy assays revealed that these EVs showed an increase in the quantity and size of ZIKV infection to differences in mock conditions. Furthermore, EVs isolated from infected cells showed infectivity, and both RNA and viral proteins were detected. Finally, our cryo-microscopy analysis revealed that the viral infection promoted morphological changes in these extracellular vesicles to identify vesicles with double and triple vesicles and electrodense and double membranes. In conclusion, our data suggest that ZIKV infection can modulate cellular factors involved in the formation and morphology of EVs in HUVECs. Furthermore, these EVs carry viral elements that may contribute to the dissemination of infection. Future studies aimed at the proteomic and lipidomic composition analyses of these EVs are needed to understand the biological implications in vertical infection.
