Comparative analysis of social issues toward medical abortion using mifepristone in South Korea and the United States: Topic modeling and sentiment analysis.
Article in PloS one, 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
This study aimed to compare social issues influencing the use of mifepristone for medical abortion between South Korea and the United States by analyzing media coverage through text mining techniques. News articles published between 2006 and 2022 related to mifepristone were collected using web scraping from representative news platforms in both countries. The collected data underwent preprocessing, followed by text analysis using the bag-of-words model. Topic modeling was conducted through Latent Dirichlet Allocation, and sentiment analysis involved using the lexicon-based methods specific to Korean and English texts. Analysis of 7,938 Korean and 650 United States articles revealed distinct patterns in media discourse on mifepristone and medical abortion. The United States coverage was polarized, encompassing clinical, legal, and access-related debates, whereas Korean articles prioritized access barriers, safety concerns, and the urgency for domestic approval, reflecting predominantly negative sentiments related to cultural stigma. This study highlights differences in the media portrayals and public perceptions of mifepristone between South Korea and the United States, underscoring the influence of regulatory contexts, public concerns and cultural attitudes on medical abortion discourse.
