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

BACKGROUND &

aimsThere is evidence that immune dysfunction precedes symptoms of inflammatory bowel disease (IBD) by several years. Characterization of preclinical systemic inflammation could contribute to the understanding of the biology of IBD and, ultimately, facilitate development of strategies for early disease detection and intervention. We evaluated associations between circulating levels of interleukin-6 (IL6) and high-sensitivity C-reactive protein (hsCRP) and diagnosis of incident Crohn's disease (CD) or ulcerative colitis (UC).

methodsWe conducted a nested case-control study of participants enrolled in 2 population-based, nationwide, prospective cohort studies (the Nurses' Health Study and the Nurses' Health Study II). We analyzed blood specimens, collected before diagnosis, from 83 persons with CD, 90 persons with UC, and 344 matched individuals without IBD (control subjects). Plasma levels of hsCRP and IL6 were measured. We investigated associations between each inflammatory marker and IBD risk using multivariable logistic regression models to adjust for potential confounding exposures.

resultsCompared with the lowest quintile of IL6 level, the highest quintile was associated with an odds ratio (OR) of 4.68 (95% confidence interval, 1.91-11.46) for CD (Ptrend < .001) and an OR of 3.43 (95% confidence interval, 1.44-8.15) for UC (Ptrend = .004). The highest quintile of hsCRP level, compared with the lowest quintile, was associated with an OR of 2.82 (95% confidence interval, 1.15-6.87) for CD (Ptrend = .019) and an OR of 1.79 (95% confidence interval, 0.80-3.99) for UC (Ptrend = .015).

conclusionsPlasma levels of IL6 and hsCRP before diagnosis are associated with risk of incident CD and UC. Subclinical levels of systemic inflammation may be a feature of an early disease state that precedes the development of symptomatic IBD.
