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

purposeBoth hepatic steatosis (HS) and colorectal cancer (CRC) are conditions associated with metabolic syndrome. The liver is the most frequent site of distant metastasis of CRC; however, the impact of HS on the incidence of liver metastasis of CRC is not clearly defined. Then, the correlation with the presence or absence of HS was analyzed.

methodsA total of 604 CRC patients receiving curative surgical resection who had a preoperative non-enhanced computed tomography (CT) were enrolled. The mean attenuation values (in Hounsfield units) of the liver and spleen were obtained on a plain CT slice, and the patients with liver-spleen attenuation ratio lower than 1.1 were objectively defined as HS. The clinicopathological features of these patients were analyzed, and the association between HS and the clinical features of CRC was examined.

resultsSixty-three (10.4%) among the 604 patients were diagnosed as HS. Recurrence-free survival (RFS) and hepatic RFS, but not extrahepatic RFS, were significantly higher in the group with HS (p = 0.04 and p = 0.006). However, this effect was not evident in the group of patients with obesity, defined as body mass index > 25.0. Among the stage I~III cases, HS was significantly associated with lower hepatic, but not extrahepatic, RFS. Moreover, absence of HS was an independent risk factor for hepatic RFS (p = 0.003).

conclusionMetastases of CRC are less frequent in fatty liver. Steatosis may be an unfavorable microenvironment for metastatic formation in the liver.
