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
Porcine reproductive and respiratory syndrome virus (PRRSV) keeps causing economic damages in the swine sector across the globe. There has been emergence of the European (EU) genotype of porcine reproductive and respiratory syndrome virus (Genotype-I PRRSV) in China in recent years. The presently available vaccines cannot unable to provide safeguard against PRRSV infection completely. This study was aimed to construct recombinant adenovirus expressing the ORF3 and ORF5 genes of the EU-type PRRSV strain. Then, the recombinant adenovirus vaccines for EU-type PRRSV (rAd-E3518, rAd-E35, rAd-E3 and rAd-E5) which we constructed and evaluated were constructed and identified by western blot and PCR. All recombinant adenovirus vaccines were evaluated for humoral and cellular responses and EU-type PRRSV challenge in pigs. The results showed that the group of rAd-E3518+Quil A developed higher GP3 and GP5 specific antibody responses compared to the group of rAd-E3518. The majority of the neutralizing antibody titers were higher than 1:16 (P<0.05), the fusion of IL-18 has increased significantly PRRSV-stimulated secretion of IFN-γ and IL-4 in porcine serum, the group of rAd-E3518+Quil A produced highest T-lymphocytes (CD3
