Ameliorating effect of CpG-ODN (oligodeoxynucleotide) against radiation-induced lung injury in mice.
Article in Radiation and environmental biophysics, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
While radiation-induced lung injury (RILI) is known to be progressed by Th2 skewed, pro-inflammatory immune response, there have been few therapeutic attempts through Th1 immune modulation. We investigated whether the immunostimulant CpG-oligodeoxynucleotide (CpG-ODN) would be effective against RILI by way of measuring reactive oxygen species (ROS) and nitric oxides (NO), histopathology, micro-three-dimensional computer tomography (CT), and cytokine profiling. We found that KSK CpG-ODN (K-CpG) significantly reduced histopathological fibrosis when compared to the positive control (PC) group (p < 0.01). The levels of ROS production in serum and splenocyte of PC group were significantly higher than that of K-CpG group (p < 0.01). The production of nitric oxide (NO) in CpG-ODNs group was higher than that of PC group. Last, cytokine profiling illustrated that the protein concentrations of Th1-type cytokines such as IL-12 and TNF-α as well as Th2-type cytokine IL-5 in K-CpG group inclined to be significantly (p < 0.001 or p < 0.01) higher than those of in PC group. Collectively, our study clearly indicates that K-CpG is effective against RILI in mice by modulating the innate immune response. To our knowledge, this is the first note on anti-RILI effect of human type, K-CpG, clinically implying the potential of immunotherapy for RILI control.
