Trends over 50 years with liberal abortion laws in the Nordic countries.
Article in PloS one, 2024. 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
backgroundDuring the 1970s the Nordic countries liberalized their abortion laws.
objectiveWe assessed epidemiological trends for induced abortion on all Nordic countries, considered legal similarities and diversities, effects of new medical innovations and changes in practical and legal provisions during the subsequent years.
methodsNew legislation strengthened surveillance of induced abortion in all countries and mandated hospitals that performed abortions to report to national abortion registers. Published data from the Nordic abortion registers were considered and new comparative analyses done. The data cover complete national populations. RESULTS AND
conclusionsAfter an increase in abortion rates during the first years following liberalization, the general abortion rates stabilized and even decreased in all Nordic countries, especially for women under 25 years. From the mid-1980s higher awareness about pregnancy termination led women to present at an earlier gestational age, which was accelerated by the introduction of medical abortion some years later. Most terminations (80-86%) are now done before the 9th gestational week in all countries, primarily by medical rather than surgical means. Introduction of routine ultrasound screening in pregnancy during the late 1980s, increased the number of 2nd trimester abortions on fetal anomaly indications without an overall increase in the proportion of 2nd relative to 1st trimester abortions. Further refinement of ultrasound screening and non-invasive prenatal diagnostic methods led to a slight increase in the proportion of early 2nd trimester abortions after the year 2000. Country-specific differences in abortion rates have remained stable over the 50 years of liberalized abortion laws.
