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

backgroundHepatocyte growth factor (HGF) is a growth factor thought to attenuate Th2-driven eosinophilic airway inflammatory responses. Increased expression of HGF and its receptor c-Met in nasal polyps suggests a role in disease pathogenesis. The effect of HGF on human sinonasal epithelial cell (SNEC) responses to Th2 inflammatory cytokines in chronic rhinosinusitis with nasal polyps (CRSwNP) has not been explored.

methodsSNECs isolated from patients with CRSwNP and control subjects were grown in cell culture at the air-liquid interface. The Th2 cytokine IL-13 was applied for 24 hours in the presence or absence of HGF. Eotaxin-3 and c-Met expression was assessed using real-time PCR, immunohistochemistry, and flow cytometry.

resultsSNECs obtained from both CRSwNP and control subjects showed markedly increased expression of eotaxin-3 after exposure to IL-13. HGF significantly blocked IL-13-induced expression of eotaxin-3 in control SNECs, but not in SNECs derived from CRSwNP subjects.

conclusionSNECs are active participants in sinonasal mucosal immunity, expressing inflammatory mediators in response to potential pathogens and endogenous cytokines. Although Th2 cytokines can elicit expression of proeosinophilic mediators by SNECs, HGF appears to have a down-regulating effect on this response. In patients with CRSwNP, SNECs are resistant to this attenuation, showing continued IL-13-induced eotaxin-3 expression despite HGF treatment. Abnormalities in the regulation of epithelial cell responses to endogenous cytokines and growth factors may contribute to the persistent eosinophilic inflammatory state in CRSwNP.
