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

backgroundVitamin D, as potential immune modulator, has been implicated as an environmental risk factor for Crohn's disease (CD). Vitamin D status may be associated with disease risk, severity, activity, and progression. While associations between circulating 25OHD and markers of disease activity and inflammation in CD have been reported, the results are inconsistent.

aimTo determine the association between vitamin D status and markers of disease activity and inflammation in CD.

methodsOne hundred and nineteen CD patients' active and inactive diseases were enrolled in the cross-sectional study. Subject demographics and clinical data were collected. A serum sample was collected for 25OHD and CRP analysis, and a stool sample was collected for fecal calprotectin (FC) measurement.

resultsThe mean serum 25OHD concentration of the group was 59.8 (24.9) nmol/L. After controlling for confounding variables, serum 25OHD inversely correlated with FC (r = -0.207, P = 0.030), particularly among those in clinical remission (r = -0.242, P = 0.022). The association between FC and 25OHD was further confirmed by linear regression (r = 31.3 %, P < 0.001). FC was lower in patients with 25OHD levels ≥75 nmol/L compared with levels <25 nmol/L [FC: 32.2 (16.3-98.2) vs 100.0 (34.4-213.5) μg/g, P = 0.004]. In the current study, however, 25OHD was not significantly associated with either CRP or CDAI.

conclusionCirculating 25OHD was significantly inversely associated with intestinal inflammation as determined by FC in CD. Subgroup analysis confirmed the association among those in clinical remission, but not in those with active disease. 25OHD was not associated with disease activity score (CDAI) or systemic inflammation (CRP). Vitamin D intervention studies are warranted to determine whether raising serum 25OHD levels in patients with CD may reduce intestinal inflammation as measured by FC.
