IL-8 inflammatory mediator secretion following ISO WS and VP exposures, by exposure condition. Data are median, IQR, and range, and the laboratory color coded points represent the mean of each laboratory results. (A) IL8 concentration. (B) IL8 concentration normalized to NRU viability. Abbreviations: AIR, air control; ALI, air–liquid interface control; INC, incubator control; ISO, International Organization for Standardization; IL-8, interleukin 8; VP, vapor phase; WS, whole smoke. *p < 0.05 compared to air control. *p < 0.05 compared to air control. Graphs were generated with R version 3.4.3 (2017-11-30) and edited by using GIMP image manipulation program (version 2.10.14).
