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

backgroundLithium accumulates in the colon and inhibits the enzyme GSK-3β that possesses anti-carcinogenic effects. We therefore examined the association between lithium use and colorectal cancer risk in a nationwide study.

methodsWe used the Danish Cancer Registry to identify all patients diagnosed with incident colorectal adenocarcinoma during 2000-2012 (n=36 248). Using a matched case-control approach, we estimated the association between long-term use (⩾5 years) of lithium and risk of colorectal adenocarcinoma using conditional logistic regression.

resultsLong-term use of lithium was similar among cases (0.22%) and controls (0.20%), yielding an odds ratio of 1.13 (95% confidence interval (CI), 0.89-1.43) for colorectal adenocarcinoma. Dose-response, subgroup and other subanalyses returned neutral associations. However, ORs differed for colorectal subsites (proximal colon: 1.01 (95% CI, 0.66-1.55; distal colon: 1.52 (95% CI, 1.05-2.20); and rectum: 0.80 (95% CI, 0.50-1.30).

conclusionsLithium use was not associated with an overall increased risk of colorectal adenocarcinoma. The variation by subsite warrants further investigation.
