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
This study aimed to construct the dual-gene expression vector pHsa-miR16-siRNA which can express human miR-16 and HBV X siRNA, and examine its regulatory effect on HBV gene expression in the HepG2.2.15 cell line. The expression vectors siR-1583 and pHsa-miR16-siRNA were designed and constructed. HepG2.2.15 cells were transfected with the empty vector, siR-1583, pmiR-16 and pHsa-miR16-siRNA, respectively. ELISA was performed to measure the expression of HBsAg and HBeAg in the culture supernatant 48 and72 h post transfection. Fluorescence quantitative PCR was used to measure the HBV mRNA degradation efficiency and HBV DNA copy number. The results showed that the expression of HBV genes was significantly inhibited in HepG2.2.15 cells transfected with siR-1583, pmiR-16 and pHsa-miR16-siRNA, respectively, when compared with that in cells transfected with the empty vectors, with the inhibitory effect of pHsa-miR16-siRNA being the most significant. ELISA showed that the inhibitory rates of HBsAg and HBeAg in pHsa-miR16-siRNA transfected cells were correspondingly 87.3% and 85.0% at 48 h, and 88.6% and 86.5% at 72 h post transfection (P<0.01 vs. control group). RT-PCR showed that the level of HBV mRNA decreased by 80.2% (t=-99.22, P<0.01), the genomic HBV DNA by 92.8% (t=-73.06, P<0.01), and the supernatant of HBV DNA copy number by 89.8% (t=-47.13, P<0.01) in pHsa-miR16-siRNA transfected group. It was suggested that the dual-gene expression vector pHsa-miR16-siRNA can inhibit the replication of HBV more efficiently than a single-gene expression vector.
