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

aimsCholangiocarcinoma (CCA) is the second most common primary liver cancer in the world. Due to the lack of effective treatments, the survival rate of CCA is low and it is usually considered difficult to diagnose early. To date, no effective strategies for the prevention of CCA have been developed. Statins are cholesterol-lowering agents which possess pleiotropic properties and the use of statins may reduce cancer risk. The aim of the study was to investigate the effect of statin use on the risk of CCA.

methodsWe used nationwide insurance data to perform a case-control study including 3174 CCA patients diagnosed in 2002-2011 and 3174 propensity score matched controls. Odds ratios (ORs) and 95% confidence intervals (CI) were calculated to assess the association between CCA risk and statin use by type of statin and dose.

resultsPatients with CCA were slightly younger than controls with mean ages of 67.4 (SD 12.3) and 68.5 (SD 13.2) years (P = 0.001), respectively, and had less users of statins (22.7 vs. 26.5%, P < 0.001). The overall adjusted OR of statin use associated CCA was 0.80 (95% CI 0.71, 0.90) and lowered for those with longer medications. The OR ranged from 0.65 to 0.77. Stronger dose-response association was seen when using lovastatin.

conclusionsStatin use is associated with reduced risk of CCA and there is a dose-response relationship between the use of statins and risk of CCA.
