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

backgroundIntrahepatic cholangiocarcinoma (ICC) has a high recurrence rate and a poor prognosis. Thus, the development of effective treatment and prognostic biomarkers is required. High expression of diacylglycerol kinase alpha (DGKα) is a prognostic factor for the recurrence of hepatocellular carcinoma. However, the relationship between DGKα expression and prognosis in ICC has not been reported.

methodsImmunohistochemistry (IHC) with anti-DGKα antibody was performed on surgical specimens of ICC (n = 69). First, DGKα expression in cancer cells was qualitatively classified into four groups (-, 1+, 2+, 3+) and divided into two groups (DGKα- and DGKα+1 + to 3+). The relationship between clinical features and DGKα expression was analyzed. Second, Ki-67 expression was evaluated as a cell proliferation marker. The number of Ki-67-positive cells was counted, and the relationship with DGKα expression was examined.

resultsDGKα IHC divided the patients into a DGKα+ group (1+: n = 15; 2+: n = 5; 3+: n = 5) and a DGKα- group (-: n = 44). In the DGKα+ group, patients were older and had advanced disease. Both overall survival and recurrence-free survival (RFS) were significantly worse in the DGKα+ patients. DGKα+ was identified as an independent prognostic factor for RFS by multivariate analysis. Furthermore, the number of Ki-67-positive cells increased in association with the staining levels of DGKα.

conclusionPathological DGKα expression in ICC was a cancer proliferation marker associated with recurrence. This suggests that DGKα may be a potential therapeutic target for ICC.
