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

The tumor suppressor FBXW7 has been demonstrated to degrade several oncoproteins, including c-Myc. Although low FBXW7 expression levels are suggested to be a poor prognostic factor in a number of types of solid tumor, the role of FBXW7 in chemosensitivity is controversial. The purpose of the present study was to determine whether FBXW7 expression may be used as a marker for poor prognosis and chemosensitivity in patients with cholangiocarcinoma (CC). FBXW7 expression was investigated by immunohistochemistry in 100 surgically resected CC samples, and the association between FBXW7 expression, clinicopathological factors and prognosis was evaluated. Nuclear FBXW7 expression tended to be lower compared with normal tissues. A total of 54 patients exhibited high expression levels of FBXW7, and 46 patients exhibited low expression levels. Patients with low FBXW7 expression possessed significantly larger tumors (P=0.049), enhanced expression of c-Myc and Ki-67 and significantly poorer prognoses compared with those with high FBXW7 expression (P=0.016). Multivariate analysis revealed that low FBXW7 expression was an independent negative prognostic factor in CC (P=0.043). In patients with high FBXW7 expression levels, the cancer-specific survival times were not significantly different between patients with or without chemotherapy. However, in patients with low FBXW7 expression levels, the cancer-specific survival times were significantly longer in subjects who underwent chemotherapy compared with those who did not (P=0.001). These data suggest that FBXW7 status in CC is a useful predictor of poor prognosis and cancer progression. Additionally, FBXW7 may be a surrogate marker to predict the efficacy of chemotherapy in CC.
