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

purposeIntracellular antioxidant enzymes are commonly upregulated in various cancer types and are associated with treatment outcomes. Because the relationship has rarely been examined in oral squamous cell carcinoma (OSCC), we aimed to evaluate the association between the levels of glutathione peroxidase (GPX)1, GPX4, and thioredoxin reductase (TrxR)1 expression and prognosis in patients with OSCC who underwent curative surgical resection.

methodsThis study included 233 patients who underwent curative surgery for previously untreated OSCC between 2000 and 2012. Tumour GPX1, GPX4, and TrxR1 expression was evaluated by immunohistochemistry and was dichotomised to low and high values according to defined expression levels. The association between GPX1, GPX4, and TrxR1 expression and clinicopathological results was analysed. Univariate and multivariate analyses using the Cox proportional hazards model were conducted to assess the significance of differences in recurrence or survival outcomes between variables.

resultsHigh GPX1, GPX4, and TrxR1 expression was observed in 99 (42.5%), 133 (57.1%), and 46 (19.7%) patients, respectively. GPX1 overexpression was significantly correlated with nodal metastasis, advanced overall stage, depth of invasion of >10 mm, high grade and perineural invasion (P < 0.05). High GPX4 expression was also related to nodal metastasis, overall advanced stage and high grade (P < 0.05). Univariate and multivariate analyses showed that increased GPX1 expression was significantly associated with poor disease-free, cancer-specific and overall survival (all P < 0.05), while increased GPX4 or TrxR1 expression was not (all P > 0.1).

conclusionsTumour GPX1 expression is a useful biomarker predictive of recurrence and survival in OSCC patients.
