The Decline of Abortion in Spain Over the Last Decade.
Article in Perspectives on sexual and reproductive health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectiveTo analyze how shifts in population composition and variations in the behavior of different sociodemographic groups have changed abortion practices in Spain between 2011 and 2021.
methodsWe used data from the Voluntary Terminations of Pregnancies register and Spanish Population and Housing Censuses to examine abortion rates and demographic characteristics of women aged 12-52. We used Poisson regression models and the Oaxaca-Blinder decomposition technique to estimate the contributions of shifts in population structure and variations in behaviors to changes in abortion rates.
resultsWe found that 40% of the decline was due to changes in sociodemographic characteristics. Specifically, the relative reduction in the number of younger women in the population and the increase in women's education levels significantly contributed to the decline in abortion rates, while the influx of immigrant women offset some of this reduction. The reduction not explained by these factors was attributed to behavioral changes, with significant reductions in the likelihood of undertaking an abortion also occurring among women under 35, immigrants from non-high-income countries, and lower-educated women.
conclusionsThe study highlights the importance of including changes in the sociodemographic composition of populations in analyses of shifts in abortion rates. It also shows that behavioral changes are not uniform, and that the primary driver of change in abortion rates in Spain is the reduction in abortion rates among the subgroups that had the highest initial rates, leading to a gradual flattening of the differences between women of different ages, education levels, and migratory backgrounds.
