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

objectivesPeroxiredoxin 4 (Prx 4) is a newly emerging antioxidant protein that has been studied in several human cancers. Recently, it was revealed that Prx 4 is highly expressed in human lung cancer and is needed for the promotion of lung cancer progression in vitro. However, there are no clinical data regarding the association of Prx 4 and prognosis in lung cancer. MATERIALS AND

methodsThe Prx 4 expression state as a prognostic indicator was assessed by immunohistochemical staining in 142 patients with stage II non-small cell lung cancer (NSCLC) who had undergone curative surgery between 2006 and 2010. The association between the degree of Prx 4 expression and several clinicopathologic parameters was then evaluated by statistical analyses.

resultsThe degree of Prx 4 expression was associated with histology and recurrence in the overall NSCLC patient group, with the proportion of patients with positive Prx 4 expression significantly higher for the adenocarcinoma subtype (39/70, 56%) than the squamous cell carcinoma subtype (23/72, 32%) (P = 0.004). However, when subgroup analyses according to histopathology were performed in terms of recurrence, positive Prx 4 expression was significantly correlated with higher recurrence rates (P = 0.003) and shorter disease-free survival (DFS) (P = 0.003, hazard ratio = 3.910) in patients with squamous cell carcinoma. In contrast, no meaningful relationship was observed between the level of Prx 4 expression and DFS in the adenocarcinoma subgroup.

conclusionPositive Prx 4 expression is significantly correlated with recurrence and shorter DFS in patients with early-stage lung squamous cell carcinoma.
