Fig. 4From: Impact of bronchoalveolar lavage lymphocytosis on the effects of anti-inflammatory therapy in idiopathic non-specific interstitial pneumonia, idiopathic pleuroparenchymal fibroelastosis, and unclassifiable idiopathic interstitial pneumoniaKaplan–Meier plot of survival probability. BAL bronchoalveolar lavage, IPF idiopathic pulmonary fibrosis, OS overall survival. For patients treated with anti-inflammatory drugs, patients with BAL lymphocytosis have longer OS than those without BAL lymphocytosis (log-rank test, P = .012) (a). On the other hand, limited to patients without anti-inflammatory drugs, no significant difference in OS is seen between patients with and without BAL lymphocytosis (log-rank test, P = 0.209) (b)Back to article page
