Pre-pregnancy characteristics, medical conditions and prenatal support among pregnant women in same-sex relationships: a population-based cohort study.
Article in Reproductive health, 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
backgroundLimited research exists on the obstetric risk profiles of women in same-sex relationships (WSSR) undergoing childbirth.
methodsPopulation-based cohort study including deliveries in the Swedish Stockholm-Gotland regions, January 2008-June 2020. Linkage with national health and quality registers provided data on relationships status. Characteristics of WSSR were compared with those of women in different-sex relationships.
resultsOf the 289 979 included deliveries, 1 292 (0.45%) were to WSSR. Compared to women in different-sex relationships, WSSR were more likely to be older, nulliparous, of Swedish origin, and have higher educational attainment. Assisted reproduction was reported for 87.5% of WSSR, versus 7.2% in the comparison group. Smoking during pregnancy was less common for WSSR (1.2% vs. 3.8%). Adjusting for parity and age, WSSR were more likely to be overweight in early pregnancy (adjusted odds ratio [aOR] 1.47; 95% CI 1.30–1.67). Furthermore, they were more likely to have received support for fear of childbirth (12.2% vs. 9.7%; aOR 1.48 95% CI 1.14–1.91). Self-rated pre-pregnancy health and history of major medical conditions were largely similar across both groups, although WSSR were more likely to have been diagnosed with thyroid conditions, rheumatic diseases, gynecological conditions and psychiatric illnesses.
conclusionsWhen undergoing childbirth, WSSR more often presented with obstetric risk factors including higher age, nulliparity, and overweight. However, they were also more likely to have higher educational attainment and less likely to report smoking. Pre-pregnancy medical conditions were largely similar between groups. Even so, psychiatric disease and support for fear of childbirth were more common in WSSR, highlighting the need for targeted support during pregnancy.
