  1. aNSNV: Nonsmoke/nonventilated; NSV: Ventilation alone; PMN: Polymorphonuclear; SNV: Smoke/nonventilated; SV: Mechanical ventilation. Data presented are the cell differentials (percentage of cells) and the absolute cell numbers in the bronchoalveolar lavage for all cells combined and among different cell types. *P < 0.05 vs. NSNV; +P < 0.05 vs. NSV.
