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
INTRODUCTION/
backgroundSevere fever with thrombocytopenia syndrome virus (SFTSV) poses a threat to global public health with a mortality rate of up to 30%. However, there is currently no commercialized SFTSV vaccine. This study focused on the construction of DNA vaccines with different structures based on the surface glycoproteins Gn and Gc to identify the immunodominant conformations.
methodsThe DNA vaccines encoding secretory proteins including Gn or Gc monomer, heterodimer of Gn and Gc (dimer), two forms of hexamer composed of the Gn and Gc heterodimer (hexamer-1 and hexamer-2) or ferritin nanoparticles of Gn, and non-secretory proteins including Gn (Gn-TM) and Gc (Gc-TM) were constructed. Western blot confirmed the expression level and the specificity of those DNA vaccines. After vaccinating mice with those DNA vaccines, its induced humoral and cellular immunity were comprehensively evaluated.
resultsThe DNA vaccines were constructed successfully. The DNA vaccines of Gn and polymers including dimer, hexamer-2, and ferritin nanoparticles inducing stronger binding antibody, neutralizing antibody, and antibody-dependent cellular cytotoxicity (ADCC) activity. The neutralizing antibody induced by these constructs was also cross-recognized by other five SFTSV pseudovirus strains. However, the T cell response induced by Gc, dimer or hexamer-2 DNA vaccines were significantly higher than those in most other groups, including Gn.
conclusionThe DNA vaccines encoding dimer or hexamer-2 demonstrated superior immunogenicity over other conformations, after taking the results of humoral and cellular responses into account. This study revealed the advantages of using polymer conformations in SFTSV vaccine design and provided new targets in SFTSV vaccine development.
