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

Virulence-associated DEAD-box RNA helicase (VAD1) is an important factor regulating the virulence of Cryptococcus neoformans. We established a real-time quantitative polymerase chain reaction (PCR) assay to measure the expression of VAD1 mRNA in the cerebrospinal fluid (CSF) of C. neoformans meningitis (CNM) patients, and we also detected the levels of IFN-γ, IL-12 and IL-10 proteins in these CSF samples and controls. Patients with head injuries were selected as controls. We found that the expression of VAD1 mRNA was significantly higher in the acute phase than in the stable phase of CNM. The level of CSF IFN-γ and IL-10 in the acute phase (9.45 pg/ml ± 2.06 and 36.28 pg/ml ± 10.86, respectively) were different to that in the controls (11.89 pg/ml ± 1.75 and 7.33 pg/ml ± 1.68, respectively). The IFN-γ/IL-10 and IL-12/IL-10 ratios were significantly higher in controls than in the acute phase, but lower than in the stable phase. The expression of VAD1 mRNA is inversely related to IFN-γ and is correlated with IL-10 but not to IL-12. The Th2 response is dominant in the acute phase, whereas the immune response switches to a Th1 response in the stable phase. The expression of VAD1 mRNA is related to the imbalance of Th1-Th2 responses, which could be one of the mechanisms by which C. neoformans escapes the immune system.
