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

backgroundInflammatory bowel disease (IBD) can adversely affect conception and pregnancy outcomes. Disease management must balance the benefits and risks for both mother and foetus.

aimTo investigate real-world pregnancy incidence and treatment patterns among women with IBD.

methodsThis retrospective, observational study used data from the Merative

resultsAmong 59,652 patients with CD and 50,452 patients with UC, pregnancy incidence was lower for patients with IBD vs. non-IBD matched controls (incidence rate ratio [95% confidence interval]: CD, 0.78 [0.76, 0.80]; UC, 0.76 [0.74, 0.78]). Treatment patterns were assessed among 3862 and 3269 pregnancies from 3235 and 2785 patients with CD and UC, respectively. Medication use was generally lower during pregnancy vs. before or after pregnancy. The most common medications were biologics for CD (23.6-34.1% across trimesters) and aminosalicylates for UC (25.0-34.9%). Pre-conception counselling and IBD-related surgery/hospitalisation were associated with increased biologic use during pregnancy.

conclusionsPatients with vs. without IBD had lower rates of pregnancy. Treatment patterns in recent years reflect current guidelines for IBD management during pregnancy. Pre-conception counselling should be emphasized.
