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

An association between hematological cancers and inflammatory bowel disease (IBD) has previously been suggested, but the risk of IBD in patients with myeloproliferative neoplasms (MPNs) is unknown. We conducted a nationwide population-based cohort study using Danish registries, to estimate the risk of IBD in individuals diagnosed with essential thrombocythemia, polycythemia vera, myelofibrosis or unclassifiable MPN during 1994-2013. MPN patients were matched 1:10 with sex- and age-matched comparisons. Everyone was followed until a diagnosis of IBD, death/emigration, or 31 December 2013. The risk of IBD overall and according to MPN subtype was calculated using Cox regression and presented as hazard ratios (HRs) with 95% confidence intervals (CI). Of 8207 MPN patients followed for 45,232 person-years, 80 were diagnosed with IBD (61 ulcerative colitis, 19 Crohn's disease). The rate of IBD per 1000 person-years was 1.8 (95% CI:1.4-2.2) in patients vs. 0.8 (95% CI:0.7-0.8) in comparisons, and the absolute 10-year risk of IBD was 0.8% (95% CI:0.6-1.0) in patients vs. 0.4% (95% CI:0.4-0.5) in comparisons. The HR of IBD was 2.4 (95% CI:2.1-2.9) with similar HRs for ulcerative colitis and Crohn's disease. MPN subtype risks varied from 2.1 (95% CI:1.6-2.7) to 2.8 (95% CI:2.1-3.7). Our unselected cohort study showed a more than 2-fold increased risk of IBD in MPN patients.
