Hormone Therapy for Cancer Is a Risk Factor for Relapse of Inflammatory Bowel Diseases.
Article in Clinical gastroenterology and hepatology : the official clinical practice journal of the American Gastroenterological Association, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers.
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.
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 &
aimsExposure to hormone contraception has been associated with an increased risk of relapse of inflammatory bowel diseases (IBDs). Little is known about the effects of cancer therapies, specifically hormone therapies, on the course of IBD.
methodsWe conducted a retrospective cohort study, collecting data from 5 medical centers, on patients with IBD who received a subsequent diagnosis of breast or prostate cancer from 1997 through 2018. For patients with quiescent IBD at their cancer diagnosis, the primary outcome was relapse of IBD. For patients with active IBD at their cancer diagnosis, the primary outcome was IBD remission.
resultsOur analysis included 447 patients with IBD (44% with Crohn's disease, 53% with ulcerative colitis, and 3% with IBD unclassified) who had either breast (78%) or prostate (22%) cancer. At their cancer diagnosis, 400 patients (90%) had inactive IBD, and 47 (10%) had active IBD. Among patients with inactive IBD, 112 (28%) developed active IBD. Previous exposure to steroids, immunomodulators, or biologics was associated with IBD relapse after a cancer diagnosis (hazard ratio [HR] for steroids, 1.79; 95% CI, 1.18-2.71; HR for immunomodulators, 2.22; 95% CI, 1.38-3.55; HR for biologics, 1.95; 95% CI, 1.01-5.36). Hormone monotherapy (HR, 2.00; 95% CI, 1.21-3.29) and combination cytotoxic and hormone therapy (HR, 1.86; 95% CI, 1.01-3.43) was associated with IBD relapse. Among 34 patients who received only cytotoxic chemotherapy, 75% remained in remission from IBD at 250 months compared with 42% of those who received hormone monotherapy (log rank, 0.02). Among patients with active IBD at their cancer diagnosis, 14 (30%) entered remission from IBD, but there were no significant factors of achieving IBD remission.
conclusionsIn a multicenter retrospective study, we found that patients with IBD and breast or prostate cancer who receive hormone therapy have an increased risk for relapse of IBD and related adverse outcomes.
