    This study identified three clinical phenotypes of pediatric community-acquired pneumonia using unsupervised machine learning techniques.

  • 2

    The Mixed-Infection phenotype, characterized by multi-pathogen coinfection, was associated with prolonged hospitalization.

  • 3

    A prediction model based on white blood cell count, lactate dehydrogenase, and procalcitonin achieved high accuracy in identifying the Mixed-Infection phenotype.

  • 4

    The study utilized bronchoalveolar lavage fluid to capture microbiological and inflammatory data, enhancing the understanding of pathogen-host interactions.

  • 5

    Further validation in larger cohorts is necessary to confirm the generalizability and clinical applicability of the developed prediction model.
