Sex differences in work-related accidents extracted from free text in Spanish using natural language processing.
Article in BMC public health, 2025. 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
backgroundEvidence from the global north shows that women and men significantly differ in work accidents and occupational disease rates. However, more data is needed for countries elsewhere.
methodsUsing natural language processing (NLP), we extracted accident mechanisms from 350,000 admission reports from the largest occupational health provider in Chile. In addition, using the same technique, we normalize occupations written in free text, following the nomenclature from the International Labour Organization (ILO).
resultsWe found that in 57.3% of accidents, a man is affected, while in 42.7% is a woman. The most common occupation for men is operator, while for women, it is related to cleaning duties. The most common form of accident for women is falling from the same height while for men is contact with sharp objects. In this work, we demonstrate the power of NLP in the massive analysis of work-related accidents by reporting the use of large language models with human expert annotation to evaluate mechanisms extraction.
conclusionBy sharing our prompts and code, we aim to help other institutions and countries extract crucial information from free text to a controlled vocabulary of ILO. Future work includes the analysis of commuting accidents and occupational diseases.
