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

objectivesWe conducted a systematic review and meta-analysis of the risk of advanced adenomas (AAs), colorectal cancer (CRC), and/or CRC-related death among individuals with low-risk adenomas (LRAs).

methodsWe searched PubMed and Embase for studies published between January 2006 and July 2015. Quality and strength of the evidence were rated using the Newcastle-Ottawa Scale (NOS) and the GRADE framework, respectively.

resultsEleven observational studies (n=64,317) were included. A meta-analysis of eight cohort studies (n=10,139, 3 to 10 years' follow-up) showed a small but statistically significant increase in the incidence of AAs in individuals with LRAs compared with those with a normal baseline colonoscopy (RR 1.55 (95% CI 1.24-1.94); P=0.0001; I

conclusionsWe observed a small but significant increase in the risk of AAs in people with LRAs compared with those with a normal baseline colonoscopy, but compared with the general population, people with LRAs have significantly lower risks of CRC and of CRC-related mortality.
