Correction to: Are there differences among operators in false-negative rates of endosonography with needle aspiration for mediastinal nodal staging of non-small cell lung cancer? (BMC Pulmonary Medicine (2018) 19 (14) DOI: 10.1186/s12890-018-0774-6)

Abstract

Following publication of the original article [1], the author flagged that the "True negative" values given in Table 1, for "Excluding patients with inaccessible LNs", were wrong for "Adenocarcinoma", "Squamous cell carcinoma" and "Others". The (incorrect) values previously given were 273 (46.0) for "Adenocarcinoma", 44 (7.4) for "Squamous cell carcinoma", and a blank value for "Others". Please be advised that the correct values are: 277 (46.6) for "Adenocarcinoma". 273 (46.0) for "Squamous cell carcinoma". 44 (7.4) for "Other". The original article has now been corrected to reflect this. The publisher apologizes for this error.
