  1. Abbreviations: BALF bronchoalvolar lavage, PMN polymorphonuclear leukocyte, NA not available. Data are presented as n (%) for categorical data, mean (±SD) for parametrically distributed data, or median (interquartile range) for nonparametrically distributed data. Statistically significant differences in variables amongst three groups were calculated using one-way ANOVA with post-hoc Turkey HSD test or Kruskal-Wallis H test for continuous data; and Fisher’s exact test with a Bonferroni correction for categorical data. a statistically significance exists between SCAP and Control; b statistically significance exists between NSCAP and Control; c statistically significance exists between SCAP and NSCAP
