Comparison of DLCO% and FVC% of patients with pleural involvement versus patients without it. A Patients with pleural involvement showed significantly poorer DLCO% than patients without it. B Patients at stage IV with pleural involvement had significantly poorer DLCO% than patients without it. C Patients at stage IV showed significantly poorer DLCO% than patients at stage II. D Mean FVC% was significantly poorer in patients with pleural involvement than in patients without it. E Although the mean FVC% of patients at stage IV with pleural involvement was less than that of patients at stage IV without pleural involvement, the difference was not statistically significant. F Patients at stage IV had significantly poorer FVC% than patients at stage II. ns: non-significant. The difference of two patient groups was analyzed by independent t-test. P < .05 was considered statistically significant
