1 · What the graph read from it

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.

2 · The registry

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

Adverse Drug Events (ADEs) pose a persistent threat to patient safety and public health. This study investigates the use of large language models (LLMs) fine-tuned for both token classification and span-based named entity recognition (NER) to improve ADE detection in clinical text. Using the 2018 n2c2 Track 2 dataset, we evaluate models under both predefined (gold label) and end-to-end settings. RoBERTa Large consistently outperforms other models, particularly in identifying ADEs, which remain more challenging due to their contextual ambiguity. Token-based models generally deliver stronger performance than span-based approaches, and ensemble methods, especially majority voting and XGBoost-based aggregation, further enhance end-to-end relation extraction by mitigating individual model weaknesses. These findings highlight the potential of fine-tuned LLMs, augmented by strategic ensembling, to advance clinical NLP pipelines and support safer, more personalized healthcare.
