“Lung diffusing capacity for nitric oxide measured by two commercial devices: a randomised crossover comparison in healthy adults”. Thomas Radtke, Quintin de Groot, Sarah R. Haile, Marion Maggi, Connie C.W. Hsia and Holger Dressel. ERJ Open Res 2021; 7: 00193-2021.

This article was originally published with an error in table 2. The upper 95% confidence limit of the per cent difference in the primary end-point (diffusing capacity of the lung for nitric oxide) was incorrectly given as 15.1% and has now been corrected to −15.1% in the published article.
