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 was aimed at exploring the effects of P2X7 receptor on BV2 microglia cell injury induced by glycoprotein gp120 (gp120) and its underlying mechanisms. We used the MTS method to study the influence of different gp120 concentrations on BV2 microglia cells, and to test the degree of cell injury in each gp120 treatment group; quantitative real-time PCR (qPCR) and Western blot were used to detect the P2X7 mRNA and receptor protein expressions. Immunocytochemistry and Western blot were used to detect the P2X7 receptor expression and P65 NF-κB, respectively. We also measured the content of TNFα, IL-1β, nitric oxide (NO) and reactive oxygen species (ROS). We found that the cell survival rate generally decreased as gp120 concentration increased, and the cell survival rate of the gp120 + Brilliant Blue G (BBG) group was higher than that of the gp120 group. Western blot and qPCR results showed that the expressions of P2X7 receptor protein and mRNA were positively dose-dependent with gp120 concentration; the results of immunocytochemistry and Western blot showed that the expressions of P2X7 receptor and P65 NF-κB in the gp120 group increased significantly compared to those of the control (Ctrl) group, but those in the gp120+BBG group decreased. Taken together, these results confirmed that the P2X7 receptor is involved in gp120-induced BV2 microglial cell injury and that the underlying mechanism may be associated with the over-activation of microglia caused by P2X7 receptor up-regulation, which leads to abundant release of inflammatory factors which exert toxic effects on the cells.
