The χ2 or Fisher's exact test were used to examine categorical data. All tests were considered significant at the P < 0.05 level. Statistically significant values are in bold type. Histological subtypes in 12 cases were unknown and were excluded from the statistical analysis. BAC, bronchioloalveolar cell type; PAP, papillary type.
