The 65 patients with typical pleural pathology for TP were all alive at discharge, whereas 39 of the remaining 140 patients died in hospital (p < 0.001 by the chi-square test). Therefore, logistic regression was performed on the 140 patients who had not received a pleural biopsy or had no typical pleural pathology for TP.
