Laboratory performances for exposure to all study products. (A) Measurements of NRU cell viability, and (B) measures of variability for each test product. Values were measured at five puffs for 1R6F, 25 puffs for Vype eStick, 10 puffs for Vype ePen 3, eight puffs for glo PRO, and seven puffs for IQOS 3 DUO. Abbreviations: S, global deviation of all laboratories; SB, interlaboratory deviation between means; Sr, intra-laboratory deviation from repeatability; SR, interlaboratory deviation from reproducibility. Graphs were generated with R version 3.4.3 (2017-11-30) and edited by using GIMP image manipulation program (version 2.10.14).
