Fig. 3: Comparison of the Flan-T5 language model and regular expression approaches for zero-shot extraction of postpartum hemorrhage (PPH)-related concepts.
From: Zero-shot interpretable phenotyping of postpartum hemorrhage using large language models
The prevalence of each concept in the annotated test set is reported and compared to the model performance according to binary F1 score. The stars (*) denote that there is a significant difference (p < 0.05, McNemar test) between the regex and language model performance. PPH postpartum hemorrhage.
