Sick Leave in Patients with Inflammatory Bowel Disease Before and After Diagnosis: A Retrospective Matched Cohort Study in Germany.
Article in Epidemiologia (Basel, Switzerland), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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/
objectivesInflammatory bowel disease (IBD) can affect work participation. Evidence on sick leave among IBD patients in Germany is limited. We compared the occurrence and duration of certified sick leave between IBD patients and non-IBD controls.
methodsPractice data from the Disease Analyzer database in Germany were used. Newly diagnosed IBD patients were matched to non-IBD controls using propensity scores. Sick leave occurrence and duration were evaluated in the year before and two years after diagnosis, using logistic and zero-inflated negative binomial regression, respectively. Stratified analyses explored variations by IBD subtype, sex, and age group.
resultsSick leave occurred more frequently in IBD patients than controls pre-index (45.7% vs. 42.2%) and during the second year post-index (49.6% vs. 42.5%), consistent with higher odds in these periods (odds ratio (OR) 1.17, 95% confidence interval (CI) 1.11-1.22 and OR 1.35, 95% CI 1.29-1.42, respectively) but not during the first year post-index, when proportions were highest in both cohorts (56.2% vs. 56.4%). While median sick leave durations were low in both cohorts (0-2 days), mean durations were higher among IBD patients. In the second year post-index, IBD patients had 1.59 times (95% CI 1.50-1.69) more sick leave days than controls. Stratified analyses suggested higher sick leave estimates in ulcerative colitis than Crohn's disease, more frequent sick leave in younger patients, and longer mean sick leave durations in older patients.
conclusionsIBD is associated with a greater certified sick leave burden before and after diagnosis, although absolute differences compared with controls were modest.
