1 · What the graph read from it

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.

2 · The registry

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

backgroundThe activation of immune response driven by the eggs of Schistosoma japonicum and the subsequent secretions is the culprit behind granulomatous inflammation and liver fibrosis. Evidence suggests that PKCλ/ι participates in a variety of physiological and pathological processes, including the regulation of metabolism, growth, proliferation and differentiation of cells. However, the role of PKCλ/ι in liver disease caused by Schistosoma japonicum remains unclear.

methodsIn the present study, we observe the pathological changes of egg-induced granulomatous inflammation and fibrosis in the liver of mice infected by Schistosoma japonicum by using conditional PKCλ/ι-knockout mice and wild-type control. Immune cytokines and fibrogenic factors were analyzed by performing flow cytometry and real-time fluorescence quantitative PCR.

resultsThe results of H&E and Masson staining show that the degree of granulomatous lesions and fibrosis in the liver of the infected PKCλ/ι-knockout mice was significantly reduced compared with those of the infected wild-type mice. The mean area of single granuloma and hepatic fibrosis in the PKCλ/ι-knockout mice was significantly lower than that of the wild-type mice (85,295.10 ± 5399.30 μm

conclusionsOur data demonstrate that PKCλ/ι deficiency alleviating granulomatous inflammation and fibrosis in the liver of mice with S. japonicum infection by downregulating Th2 immune response is the potential molecular mechanism behind the role of PKCλ/ι in schistosomiasis.
