BALF cellularity mirrored peripheral cytopenias yet increased with higher Aspergillus burden and respiratory coinfections, consistent with both systemic immune availability and local inflammatory stimuli. However, BALF cellularity was not independently associated with 42-day mortality, which was driven by persistent neutropenia and critical illness. These findings suggest BALF cellularity may not be an independent determinant of short-term outcomes but rather reflects underlying host and disease context.<\/jats:p>","DOI":"10.1093\/infdis\/jiag475","type":"journal-article","created":{"date-parts":[[2026,10,2]],"date-time":"2026-10-02T11:46:36Z","timestamp":1790941596000},"source":"Crossref","is-referenced-by-count":0,"title":["Bronchoalveolar
