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

objectiveTo investigate the impact of metformin on survival of diabetic patients following surgery for colorectal cancer (CRC).

methodsThis was a retrospective cohort study. From Taiwan's population-based National Health Insurance Research Database (NHIRD) we identified 12,512 patients with CRC and type II diabetes who underwent curative surgery between 2000 and 2012. Of these, 6222 patients were included in a matched cohort. Using Cox regression models with time-dependent covariates we examined the impact of metformin on survival.

resultsAverage duration of follow-up was 49 and 54 months for metformin users and non-users, respectively. Cox proportional hazard model showed that metformin was associated with 5-year overall survival benefit (Hazard ratio, 0.23 [95% CI, 0.20-0.26]) and inverse association with risk of liver metastasis (Hazard ratio, 0.79 [95% CI, 0.68-0.93]).

conclusionsMetformin was associated with a survival benefit in diabetic patients with CRC following surgery, and an inverse association with risk of liver metastases suggesting a potential anti-tumorigenic effect.
